Exception sending context initialized event to listener instance of class org.springframework.

Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

java.lang.NoSuchMethodError: org.springframework.core.type.AnnotationMetadata.introspect(Ljava/lang/Class;)Lorg/springframework/core/type/AnnotationMetadata;

错误可能原因:

1.检查web.xml里的监听器是否配置错误

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

2.pom.xml中 spring-webmvc包要放在spring相关包之前

<!--springMVC-->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>5.2.8.RELEASE</version>
</dependency>
<!--基于AOP的事务-->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-tx</artifactId>
<version>5.1.2.RELEASE</version>
</dependency>
<!--template模板-->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>5.1.2.RELEASE</version>
</dependency>
<!--织入-->
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjweaver</artifactId>
<version>1.9.8</version>
</dependency>
<!--上下文-->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>5.2.8.RELEASE</version>
</dependency>
<!--spring测试-->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>5.2.8.RELEASE</version>
</dependency>
<!--spring-web-->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>5.2.8.RELEASE</version>
</dependency>
