Java:错误创建使用名称“ LoadTimeWeaver”的BEAN

Question

我目前正在从事一个Maven项目，但是每次尝试部署战争时，我都会得到以下例外：

ERROR [DispatcherPortlet:276] Context initialization failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.context.weaving.AspectJWeavingEnabler#0': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'loadTimeWeaver': Initialization of bean failed;  nested exception is java.lang.IllegalStateException: ClassLoader [org.apache.catalina.loader.WebappClassLoader] does NOT provide an 'addTransformer(ClassFileTransforme r)' method.

        at org.springframework.web.portlet.GenericPortletBean.init(GenericPortletBean.java:120)

我根本不明白何时正确地将所有错误都适当。请在pom.xml

中查看我的声明

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.4</version>
    <configuration>
            <forkMode>once</forkMode>
            <argLine>
                 -javaagent:"pathspring-instrument-3.1.0.RELEASE.jar"
            </argLine>
            <useSystemClassloader>true</useSystemClassloader>
    </configuration>
</plugin>

请指南。

Answer 1

如果您使用的是tomcat捆绑包并在tomcat中启用 load-time-weaving添加弹簧仪器tomcat到tomcat的lib目录，以及在tomcat的META-INF目录中的context.xml中的以下内容：

：

<Context path="/test">
    <Loader loaderClass="org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader"/>
</Context>

请参阅Tomcat配置上的春季文档。

注意：tomcat的配置根据版本有所不同。

Answer 2

尽管这个问题很久以前就问了，但我仍在回答。其他人可能会发现它有用。如果您使用的是tomcat，请尝试在catalina.bash或catalina.sh.sh for Linux服务器中添加以下内容：

set CATALINA_OPTS=%CATALINA_OPTS% -javaagent:"C:pathtospring-instrument-3.1.1.RELEASE.jar"

请记住，它仅在小于7.0.55的tomcat版本中起作用。之后，它不会接受。您需要在上下文中添加它。xml，如下所述，加载时间 - 网络（apciptj-weaver）在apache tomcat 7.0.55中不起作用。
