更新時(shí)間：2017年05月25日 11:47:42 作者：成立_ChengLi

本篇文章主要介紹了詳解Spring Boot 使用Spring security 集成CAS，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

1.創(chuàng)建工程

創(chuàng)建Maven工程：springboot-security-cas

2.加入依賴

創(chuàng)建工程后，打開pom.xml，在pom.xml中加入以下內(nèi)容：

<parent> 
    <groupId>org.springframework.boot</groupId> 
    <artifactId>spring-boot-starter-parent</artifactId> 
    <version>1.4.3.RELEASE</version> 
  </parent> 
  <properties> 
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> 
    <java.version>1.8</java.version> 
  </properties> 
  <dependencies> 
    <dependency> 
      <groupId>org.springframework.boot</groupId> 
      <artifactId>spring-boot-starter</artifactId> 
    </dependency> 
    <dependency> 
      <groupId>org.springframework.boot</groupId> 
      <artifactId>spring-boot-starter-web</artifactId> 
    </dependency> 
    <!-- security starter Poms --> 
    <dependency> 
      <groupId>org.springframework.boot</groupId> 
      <artifactId>spring-boot-starter-security</artifactId> 
    </dependency> 
    <!-- security 對CAS支持 --> 
    <dependency> 
      <groupId>org.springframework.security</groupId> 
      <artifactId>spring-security-cas</artifactId> 
    </dependency> 
    <!-- security taglibs --> 
    <dependency> 
      <groupId>org.springframework.security</groupId> 
      <artifactId>spring-security-taglibs</artifactId> 
    </dependency> 
    <!-- 熱加載 --> 
    <dependency> 
      <groupId>org.springframework.boot</groupId> 
      <artifactId>spring-boot-devtools</artifactId> 
      <optional>true</optional> 
    </dependency> 
    <dependency> 
      <groupId>org.springframework.boot</groupId> 
      <artifactId>spring-boot-configuration-processor</artifactId> 
      <optional>true</optional> 
    </dependency> 
  </dependencies> 
  <build> 
    <plugins> 
      <plugin> 
        <groupId>org.springframework.boot</groupId> 
        <artifactId>spring-boot-maven-plugin</artifactId> 
      </plugin> 
    </plugins> 
  </build>

3.創(chuàng)建application.properties

創(chuàng)建application.properties文件，加入以下內(nèi)容：

#CAS服務(wù)地址 
cas.server.host.url=http://localhost:8081/cas 
#CAS服務(wù)登錄地址 
cas.server.host.login_url=${cas.server.host.url}/login 
#CAS服務(wù)登出地址 
cas.server.host.logout_url=${cas.server.host.url}/logout?service=${app.server.host.url} 
#應(yīng)用訪問地址 
app.server.host.url=http://localhost:8080 
#應(yīng)用登錄地址 
app.login.url=/login 
#應(yīng)用登出地址 
app.logout.url=/logout

4.創(chuàng)建入口啟動(dòng)類（MainConfig）

創(chuàng)建入口啟動(dòng)類MainConfig，完整代碼如下：

package com.chengli.springboot; 
 
import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.SpringBootApplication; 
import org.springframework.security.access.prepost.PreAuthorize; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.RestController; 
 
@RestController 
@SpringBootApplication 
public class MainConfig { 
  public static void main(String[] args) { 
    SpringApplication.run(MainConfig.class, args); 
  } 
 
  @RequestMapping("/") 
  public String index() { 
    return "訪問了首頁哦"; 
  } 
 
  @RequestMapping("/hello") 
  public String hello() { 
    return "不驗(yàn)證哦"; 
  } 
 
  @PreAuthorize("hasAuthority('TEST')")//有TEST權(quán)限的才能訪問 
  @RequestMapping("/security") 
  public String security() { 
    return "hello world security"; 
  } 
 
  @PreAuthorize("hasAuthority('ADMIN')")//必須要有ADMIN權(quán)限的才能訪問 
  @RequestMapping("/authorize") 
  public String authorize() { 
    return "有權(quán)限訪問"; 
  } 
   
  /**這里注意的是，TEST與ADMIN只是權(quán)限編碼，可以自己定義一套規(guī)則，根據(jù)實(shí)際情況即可*/ 
}

5.創(chuàng)建Security配置類（SecurityConfig）

創(chuàng)建Security配置類SecurityConfig，完整代碼如下：

package com.chengli.springboot.security; 
 
import org.jasig.cas.client.session.SingleSignOutFilter; 
import org.jasig.cas.client.validation.Cas20ServiceTicketValidator; 
import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.context.annotation.Bean; 
import org.springframework.context.annotation.Configuration; 
import org.springframework.security.cas.ServiceProperties; 
import org.springframework.security.cas.authentication.CasAssertionAuthenticationToken; 
import org.springframework.security.cas.authentication.CasAuthenticationProvider; 
import org.springframework.security.cas.web.CasAuthenticationEntryPoint; 
import org.springframework.security.cas.web.CasAuthenticationFilter; 
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder; 
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity; 
import org.springframework.security.config.annotation.web.builders.HttpSecurity; 
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity; 
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter; 
import org.springframework.security.core.userdetails.AuthenticationUserDetailsService; 
import org.springframework.security.web.authentication.logout.LogoutFilter; 
import org.springframework.security.web.authentication.logout.SecurityContextLogoutHandler; 
 
import com.chengli.springboot.custom.CustomUserDetailsService; 
import com.chengli.springboot.properties.CasProperties; 
 
@Configuration 
@EnableWebSecurity //啟用web權(quán)限 
@EnableGlobalMethodSecurity(prePostEnabled = true) //啟用方法驗(yàn)證 
public class SecurityConfig extends WebSecurityConfigurerAdapter { 
  @Autowired 
  private CasProperties casProperties; 
   
  /**定義認(rèn)證用戶信息獲取來源，密碼校驗(yàn)規(guī)則等*/ 
  @Override 
  protected void configure(AuthenticationManagerBuilder auth) throws Exception { 
    super.configure(auth); 
    auth.authenticationProvider(casAuthenticationProvider()); 
    //inMemoryAuthentication 從內(nèi)存中獲取 
    //auth.inMemoryAuthentication().withUser("chengli").password("123456").roles("USER") 
    //.and().withUser("admin").password("123456").roles("ADMIN"); 
     
    //jdbcAuthentication從數(shù)據(jù)庫中獲取，但是默認(rèn)是以security提供的表結(jié)構(gòu) 
    //usersByUsernameQuery 指定查詢用戶SQL 
    //authoritiesByUsernameQuery 指定查詢權(quán)限SQL 
    //auth.jdbcAuthentication().dataSource(dataSource).usersByUsernameQuery(query).authoritiesByUsernameQuery(query); 
     
    //注入userDetailsService，需要實(shí)現(xiàn)userDetailsService接口 
    //auth.userDetailsService(userDetailsService); 
  } 
   
  /**定義安全策略*/ 
  @Override 
  protected void configure(HttpSecurity http) throws Exception { 
    http.authorizeRequests()//配置安全策略 
      //.antMatchers("/","/hello").permitAll()//定義/請求不需要驗(yàn)證 
      .anyRequest().authenticated()//其余的所有請求都需要驗(yàn)證 
      .and() 
    .logout() 
      .permitAll()//定義logout不需要驗(yàn)證 
      .and() 
    .formLogin();//使用form表單登錄 
     
    http.exceptionHandling().authenticationEntryPoint(casAuthenticationEntryPoint()) 
      .and() 
      .addFilter(casAuthenticationFilter()) 
      .addFilterBefore(casLogoutFilter(), LogoutFilter.class) 
      .addFilterBefore(singleSignOutFilter(), CasAuthenticationFilter.class); 
     
    //http.csrf().disable(); //禁用CSRF 
  } 
   
  /**認(rèn)證的入口*/ 
  @Bean 
  public CasAuthenticationEntryPoint casAuthenticationEntryPoint() { 
    CasAuthenticationEntryPoint casAuthenticationEntryPoint = new CasAuthenticationEntryPoint(); 
    casAuthenticationEntryPoint.setLoginUrl(casProperties.getCasServerLoginUrl()); 
    casAuthenticationEntryPoint.setServiceProperties(serviceProperties()); 
    return casAuthenticationEntryPoint; 
  } 
   
  /**指定service相關(guān)信息*/ 
  @Bean 
  public ServiceProperties serviceProperties() { 
    ServiceProperties serviceProperties = new ServiceProperties(); 
    serviceProperties.setService(casProperties.getAppServerUrl() + casProperties.getAppLoginUrl()); 
    serviceProperties.setAuthenticateAllArtifacts(true); 
    return serviceProperties; 
  } 
   
  /**CAS認(rèn)證過濾器*/ 
  @Bean 
  public CasAuthenticationFilter casAuthenticationFilter() throws Exception { 
    CasAuthenticationFilter casAuthenticationFilter = new CasAuthenticationFilter(); 
    casAuthenticationFilter.setAuthenticationManager(authenticationManager()); 
    casAuthenticationFilter.setFilterProcessesUrl(casProperties.getAppLoginUrl()); 
    return casAuthenticationFilter; 
  } 
   
  /**cas 認(rèn)證 Provider*/ 
  @Bean 
  public CasAuthenticationProvider casAuthenticationProvider() { 
    CasAuthenticationProvider casAuthenticationProvider = new CasAuthenticationProvider(); 
    casAuthenticationProvider.setAuthenticationUserDetailsService(customUserDetailsService()); 
    //casAuthenticationProvider.setUserDetailsService(customUserDetailsService()); //這里只是接口類型，實(shí)現(xiàn)的接口不一樣，都可以的。 
    casAuthenticationProvider.setServiceProperties(serviceProperties()); 
    casAuthenticationProvider.setTicketValidator(cas20ServiceTicketValidator()); 
    casAuthenticationProvider.setKey("casAuthenticationProviderKey"); 
    return casAuthenticationProvider; 
  } 
   
  /*@Bean 
  public UserDetailsService customUserDetailsService(){ 
    return new CustomUserDetailsService(); 
  }*/ 
   
  /**用戶自定義的AuthenticationUserDetailsService*/ 
  @Bean 
  public AuthenticationUserDetailsService<CasAssertionAuthenticationToken> customUserDetailsService(){ 
    return new CustomUserDetailsService(); 
  } 
   
  @Bean 
  public Cas20ServiceTicketValidator cas20ServiceTicketValidator() { 
    return new Cas20ServiceTicketValidator(casProperties.getCasServerUrl()); 
  } 
   
  /**單點(diǎn)登出過濾器*/ 
  @Bean 
  public SingleSignOutFilter singleSignOutFilter() { 
    SingleSignOutFilter singleSignOutFilter = new SingleSignOutFilter(); 
    singleSignOutFilter.setCasServerUrlPrefix(casProperties.getCasServerUrl()); 
    singleSignOutFilter.setIgnoreInitConfiguration(true); 
    return singleSignOutFilter; 
  } 
   
  /**請求單點(diǎn)退出過濾器*/ 
  @Bean 
  public LogoutFilter casLogoutFilter() { 
    LogoutFilter logoutFilter = new LogoutFilter(casProperties.getCasServerLogoutUrl(), new SecurityContextLogoutHandler()); 
    logoutFilter.setFilterProcessesUrl(casProperties.getAppLogoutUrl()); 
    return logoutFilter; 
  } 
}

6.用戶自定義類

（1）定義CasProperties，用于將properties文件指定的內(nèi)容注入以方便使用，這里不注入也是可以的，可以獲取Spring 當(dāng)前的環(huán)境，代碼如下：

package com.chengli.springboot.properties; 
import org.springframework.beans.factory.annotation.Value; 
import org.springframework.stereotype.Component; 
 
/** 
 * CAS的配置參數(shù) 
 * @author ChengLi 
 */ 
@Component 
public class CasProperties { 
  @Value("${cas.server.host.url}") 
  private String casServerUrl; 
 
  @Value("${cas.server.host.login_url}") 
  private String casServerLoginUrl; 
 
  @Value("${cas.server.host.logout_url}") 
  private String casServerLogoutUrl; 
 
  @Value("${app.server.host.url}") 
  private String appServerUrl; 
 
  @Value("${app.login.url}") 
  private String appLoginUrl; 
 
  @Value("${app.logout.url}") 
  private String appLogoutUrl; 
......省略 getters setters 方法 
}

（2）定義CustomUserDetailsService類，代碼如下：

package com.chengli.springboot.custom; 
 
import java.util.HashSet; 
import java.util.Set; 
 
import org.springframework.security.cas.authentication.CasAssertionAuthenticationToken; 
import org.springframework.security.core.userdetails.AuthenticationUserDetailsService; 
import org.springframework.security.core.userdetails.UserDetails; 
import org.springframework.security.core.userdetails.UsernameNotFoundException; 
 
/** 
 * 用于加載用戶信息 實(shí)現(xiàn)UserDetailsService接口，或者實(shí)現(xiàn)AuthenticationUserDetailsService接口 
 * @author ChengLi 
 * 
 */ 
public class CustomUserDetailsService /* 
  //實(shí)現(xiàn)UserDetailsService接口，實(shí)現(xiàn)loadUserByUsername方法 
  implements UserDetailsService { 
  @Override 
  public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException { 
    System.out.println("當(dāng)前的用戶名是："+username); 
    //這里我為了方便，就直接返回一個(gè)用戶信息，實(shí)際當(dāng)中這里修改為查詢數(shù)據(jù)庫或者調(diào)用服務(wù)什么的來獲取用戶信息 
    UserInfo userInfo = new UserInfo(); 
    userInfo.setUsername("admin"); 
    userInfo.setName("admin"); 
    Set<AuthorityInfo> authorities = new HashSet<AuthorityInfo>(); 
    AuthorityInfo authorityInfo = new AuthorityInfo("TEST"); 
    authorities.add(authorityInfo); 
    userInfo.setAuthorities(authorities); 
    return userInfo; 
  }*/ 
   
   
  //實(shí)現(xiàn)AuthenticationUserDetailsService，實(shí)現(xiàn)loadUserDetails方法 
  implements AuthenticationUserDetailsService<CasAssertionAuthenticationToken> { 
 
  @Override 
  public UserDetails loadUserDetails(CasAssertionAuthenticationToken token) throws UsernameNotFoundException { 
    System.out.println("當(dāng)前的用戶名是："+token.getName()); 
    /*這里我為了方便，就直接返回一個(gè)用戶信息，實(shí)際當(dāng)中這里修改為查詢數(shù)據(jù)庫或者調(diào)用服務(wù)什么的來獲取用戶信息*/ 
    UserInfo userInfo = new UserInfo(); 
    userInfo.setUsername("admin"); 
    userInfo.setName("admin"); 
    Set<AuthorityInfo> authorities = new HashSet<AuthorityInfo>(); 
    AuthorityInfo authorityInfo = new AuthorityInfo("TEST"); 
    authorities.add(authorityInfo); 
    userInfo.setAuthorities(authorities); 
    return userInfo; 
  } 
 
}

（3）定義AuthorityInfo類，用于加載當(dāng)前登錄用戶的權(quán)限信息，實(shí)現(xiàn)GrantedAuthority接口，代碼如下：

package com.chengli.springboot.custom; 
 
import org.springframework.security.core.GrantedAuthority; 
 
/** 
 * 權(quán)限信息 
 * 
 * @author ChengLi 
 * 
 */ 
public class AuthorityInfo implements GrantedAuthority { 
  private static final long serialVersionUID = -175781100474818800L; 
 
  /** 
   * 權(quán)限CODE 
   */ 
  private String authority; 
 
  public AuthorityInfo(String authority) { 
    this.authority = authority; 
  } 
 
  @Override 
  public String getAuthority() { 
    return authority; 
  } 
 
  public void setAuthority(String authority) { 
    this.authority = authority; 
  } 
 
}

（4）定義UserInfo類，用于加載當(dāng)前用戶信息，實(shí)現(xiàn)UserDetails接口，代碼如下：

package com.chengli.springboot.custom; 
 
import java.util.Collection; 
import java.util.HashSet; 
import java.util.Set; 
 
import org.springframework.security.core.GrantedAuthority; 
import org.springframework.security.core.userdetails.UserDetails; 
 
/** 
 * 用戶信息 
 * @、這里我寫了幾個(gè)較為常用的字段，id，name，username，password，可以根據(jù)實(shí)際的情況自己增加 
 * @author ChengLi 
 * 
 */ 
public class UserInfo implements UserDetails { 
  private static final long serialVersionUID = -1041327031937199938L; 
 
  /** 
   * 用戶ID 
   */ 
  private Long id; 
 
  /** 
   * 用戶名稱 
   */ 
  private String name; 
 
  /** 
   * 登錄名稱 
   */ 
  private String username; 
 
  /** 
   * 登錄密碼 
   */ 
  private String password; 
 
  private boolean isAccountNonExpired = true; 
 
  private boolean isAccountNonLocked = true; 
 
  private boolean isCredentialsNonExpired = true; 
 
  private boolean isEnabled = true; 
 
  private Set<AuthorityInfo> authorities = new HashSet<AuthorityInfo>(); 
....省略getters setters 方法 
}

到這里基本就已經(jīng)完成了，運(yùn)行CAS Server ，將以上的application.properties文件中的地址修改為實(shí)際的地址即可運(yùn)行。

以上就是本文的全部內(nèi)容，希望對大家的學(xué)習(xí)有所幫助，也希望大家多多支持腳本之家。
