這篇文章主要給大家介紹了關(guān)于SpringBoot項(xiàng)目報(bào)錯(cuò):“Error?starting?ApplicationContext.?To?display?the?conditions?report?re-run?...”的解決辦法,文中通過圖文介紹的非常詳細(xì),需要的朋友可以參考下

發(fā)現(xiàn)錯(cuò)誤

SpringBoot項(xiàng)目報(bào)錯(cuò)：

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

以下方案80%可以幫助您解決這些個(gè)‘可惡的’問題

報(bào)錯(cuò)內(nèi)容和截圖如下：

——在看到這些個(gè)問題的時(shí)候，日志基本都會(huì)告訴你錯(cuò)誤的地方，所以我們大部分可以根據(jù)日志報(bào)錯(cuò)的信息分析錯(cuò)誤的原因：

一、編譯出問題

仔細(xì)看報(bào)出的問題，有沒有如：“Description：…” 這樣的字眼，沒有 “描述”，如上圖所示，這種情況下的操作：
1.clean清理一下； 2.然后install重新編譯一下；

3.也可以用這個(gè)命令，重新編譯一下

這個(gè)時(shí)候重新啟動(dòng)，如果還是報(bào)同樣的錯(cuò)誤，打開如下圖位置，看是否有編譯的文件，如mapper.xml文件，application.yml或者application.properties文件，以及一些配置文件等

——哎！生氣，這里發(fā)現(xiàn)真的沒有mapper和配置文件，只有main下面的.jar文件，該怎么辦呢？

——pom.xml文件中給加入要編譯的文件位置依賴，如下：(這是我的文件位置，你根據(jù)你的進(jìn)行調(diào)整)

<!--引入本地資源-->
        <resources>
            <!--加載lib文件，特殊情況下會(huì)有l(wèi)ib，但大部分都靠依賴下載了-->
            <resource>
                <directory>lib</directory>
                <targetPath>BOOT-INF/lib/</targetPath>
                <includes>
                    <include>**/*.jar</include>
                </includes>
            </resource>
            <!--打jar包-->
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                </includes>
            </resource>
            <!--將properties和xml文件編譯-->
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                </includes>
                <filtering>false</filtering>
            </resource>
        </resources>

好的，清理——>打包——>啟動(dòng)——>運(yùn)行成功，搞定收工

二、請(qǐng)求接口重復(fù)

根據(jù)日志看出它說路徑問題；這樣想你寫的接口名字是否重復(fù)，只有一個(gè)斜杠或者沒斜杠的情況

如下截圖：

修改如下：

好的，重新啟動(dòng)，搞定收工

三、加@Mapper注解

這些情況就是看描述的問題

如圖：

這種情況，看是不是沒有掃描到它需要的東西，給加上@Mapper注解（是掃描dao層的），或者加上@Service注解（掃描service層）即可。

四、加@SpringBootApplication注解，數(shù)據(jù)庫(kù)問題

根據(jù)問題看出：springboot啟動(dòng)時(shí)會(huì)自動(dòng)注入數(shù)據(jù)源和配置jpa ，解決：

在@SpringBootApplication中排除其注入

@SpringBootApplication(exclude={DataSourceAutoConfiguration.class,HibernateJpaAutoConfiguration.class})

五、端口重復(fù)問題

查看是否自己的運(yùn)行端口沖突，將其kill殺死，重新啟動(dòng)，或者跟換端口

以下是查看端口沖突的方式：

window鍵+R，輸入“netstat -aon|findstr 8080”找到占用8080端口的進(jìn)程號(hào)：

2.輸入“tasklist|findstr “3412” ”：

查看進(jìn)程號(hào)為“3412”的進(jìn)程：

3.輸入“taskkill /f /t /im QQ.exe”：(/f：強(qiáng)制性的結(jié)束進(jìn)程)

結(jié)束這個(gè)進(jìn)程

現(xiàn)在可以重新啟動(dòng)一下，看是否運(yùn)行成功

六、包沖突

還有的情況可能是包沖突了，可以將maven倉(cāng)庫(kù)清理一下自己的包，重新下載一下

總結(jié)
