基于Failed to load ApplicationContext异常的解决思路

Failed to load ApplicationContext异常

在使用spring连接数据库时出现了如下异常

java.lang.IllegalStateException: Failed to load ApplicationContext

根据第一次出现Caused by：...的语句，我们锁定出现问题的原因是由于

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.

配置数据库属性时出现异常，导致时区的值无法识别，检查代码后发现是由于拼写问题

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

将serverTimeZone改为serverTimezone再次调试，发现问题解决，并不是大多数人提出的添加@ContextConfiguration("classpath:spring-transaction.xml")

代码出错后要根据自己程序的报错来具体解决

Failed to load ApplicationContext之spring最常遇到的问题汇总

遇到几个极难解决的问题

出现如上问题基本上都是配置文件的问题：

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.

这个今天是我遇到的比较典型的问题，路径配置的太大了,修改代码如下：

<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>
