Failed to load ApplicationContext異常

在使用spring連接數(shù)據(jù)庫時出現(xiàn)了如下異常

根據(jù)第一次出現(xiàn)Caused by：...的語句，我們鎖定出現(xiàn)問題的原因是由于

MybatisPlusException: Error: GlobalConfigUtils setMetaData Fail !  Cause:java.sql.SQLException: The server time zone value '?й???????' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the 'serverTimezone' configuration property) to use a more specifc time zone value if you want to utilize time zone support.

配置數(shù)據(jù)庫屬性時出現(xiàn)異常，導(dǎo)致時區(qū)的值無法識別，檢查代碼后發(fā)現(xiàn)是由于拼寫問題

spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/mybatis_plus?serverTimeZone=GMT%2B8
spring.datasource.username=root
spring.datasource.password=1996zsy1996zsy

將serverTimeZone改為serverTimezone再次調(diào)試，發(fā)現(xiàn)問題解決，并不是大多數(shù)人提出的添加@ContextConfiguration("classpath:spring-transaction.xml")

代碼出錯后要根據(jù)自己程序的報錯來具體解決

Failed to load ApplicationContext之spring最常遇到的問題匯總

遇到幾個極難解決的問題

出現(xiàn)如上問題基本上都是配置文件的問題：

jjava.lang.IllegalStateException: Failed to load ApplicationContext

org.springframework.test.context.junit4.statements.RunBeforeTestClassCallbacks.evaluate(RunBeforeTestClassCallbacks.java:61)
 at org.springframework.test.context.junit4.statements.RunAfterTestClassCallbacks.evaluate(RunAfterTestClassCallbacks.java:70)

Caused by: org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'dataSource': Bean with name 'dataSource' has been injected into other beans [transactionManager] in its raw version as part of a circular reference, but has eventually been wrapped. This means that said other beans do not use the final version of the bean. This is often the result of over-eager type matching - consider using 'getBeanNamesOfType' with the 'allowEagerInit' flag turned off, for example.

這個今天是我遇到的比較典型的問題，路徑配置的太大了,修改代碼如下：

<aop:config>
?<aop:pointcut expression="execution(* cn.itcast.service.impl.*ServiceImpl.*(..))" id="txPC"/>
?<!--<aop:pointcut expression="execution(* *..*(..))" id="txPC" />-->
?<aop:advisor advice-ref="txAdvice" pointcut-ref="txPC"/>
?</aop:config>

以上為個人經(jīng)驗，希望能給大家一個參考，也希望大家多多支持腳本之家。
