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 '������' 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：
