java.lang.NoSuchMethodError: org.springframework.core.annotation.AnnotatedElementUtils.findMergedAnnotation

Question

当我运行服务器时，我在控制台上收到以下错误：

Error creating bean with name  
org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMa
pping#0': Invocation of init method failed; nested exception is 
java.lang.NoSuchMethodError:    
org.springframework.core.annotation.AnnotatedElementUtils.findMergedAnnotation
(Ljava/lang/reflect/AnnotatedElement;Ljava/lang/Class;)Ljava/lang/annotation/Annotation;

网页出现404错误。我检查了 url 并且资源存在。

这是我的 xml 的：

Answer 1

这可能是因为多个相同的 jar 文件具有不同的版本。确保您没有多个具有不同版本 Spring.

的 jar 文件

Answer 2

您的 bean 尚未配置。在 spring-servlet.xml

中配置它

<bean id="employeeDao" class="com.abhishek.EmployeeDao">
    <property name="jdbcTemplate" ref="myJDBC"></property>
</bean>

Answer 3

还要查看以下内容。

检查你的jar包是否有需要的方法
检查相同的方法是否不能在多个 jar 中，以便它们都试图将索引提供给 jvm，而 JVM 混淆选择正确。
列出你的 jars/dependency 删除不必要的
使用maven下载需要的依赖或者从spring.io/projects,grepcode.

LAST sometime we have required jar but we do not have required method may be due to legacy etc so please choose appropriate jar for it.

Answer 4

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'requestMappingHandlerMapping' defined in class org.springframework.web.servlet.config.annotation.DelegatingWebMvcConfiguration: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping]: Factory method 'requestMappingHandlerMapping' threw exception; nested exception is java.lang.NoSuchMethodError: 'java.lang.annotation.Annotation org.springframework.core.annotation.AnnotatedElementUtils.findMergedAnnotation(java.lang.reflect.AnnotatedElement, java.lang.Class)'

我在将我们的ant项目迁移到maven项目时也遇到了同样的问题。

调试了一整天后，根据上述数据。我观察到 activemq-all 5.13.2 jar 内部包含 Spring 个罐子。

问题之前我的maven依赖。

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-jdbc</artifactId>
        <version>4.3.20.RELEASE</version>
    </dependency>
    
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc</artifactId>
        <version>4.3.20.RELEASE</version>
    </dependency>

    <dependency>
        <groupId>org.apache.activemq</groupId>
        <artifactId>activemq-all</artifactId>
        <version>5.13.2</version>
    </dependency>

在我们的ant项目中，我们使用的是activemq-all 5.9.0 jar。通过使用这个罐子，问题得到解决。由于此版本中没有 spring 罐子。

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-jdbc</artifactId>
        <version>4.3.20.RELEASE</version>
    </dependency>
    
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc</artifactId>
        <version>4.3.20.RELEASE</version>
    </dependency>

    <dependency>
        <groupId>org.apache.activemq</groupId>
        <artifactId>activemq-all</artifactId>
        <version>5.9.0</version>
    </dependency>

结论：每当遇到此类问题时，我们都需要检查依赖项正在使用的内部 jar。
