实体管理器尚未注入：是将Spring Aspects JAR配置为AJC/AJDT方面的库吗？

Question

我想写一个简单的春天休息Web服务，因为我不熟悉Maven（并且因为Maven通常不能完成任务 - 连接问题），所以我现在尝试构建Ant。现在，构建可以，服务可以运行。但是，如果持续功能被触发时，系统会提示：

01:48:39 Handler execution resulted in exception - forwarding to resolved error view: ModelAndView: reference to view with name 'uncaughtException'; model is {exception=java.lang.IllegalStateException: Entity manager has not been injected (is the Spring Aspects JAR configured as an AJC/AJDT aspects library?)} -org.springframework.web.servlet.DispatcherServlet 
java.lang.IllegalStateException: Entity manager has not been injected (is the Spring Aspects JAR configured as an AJC/AJDT aspects library?)

我的蚂蚁的build.xml：

<target name="compile" depends="init" description="compile the source "> 
    <!--<javac srcdir="${src}" 
    debug="on" 
    destdir="${build}" 
    classpathref="compile.classpath" 
    includeantruntime="false"/>--> 
    <iajc source ="1.6" target="1.6" sourceroots="src/main/java" destDir="src/main/webapp/WEB-INF/classes" showweaveinfo="true" verbose="true"> 
     <classpath> 
      <path refid="compile.classpath"/> 
      <path refid="aspectj.classpath"/> 
     </classpath> 
    </iajc> 
</target> 

我的applicationContext.xml：

<bean class="org.springframework.orm.jpa.JpaTransactionManager" id="transactionManager"> 
    <property name="entityManagerFactory" ref="entityManagerFactory"/> 
</bean> 
<tx:annotation-driven mode="aspectj" transaction-manager="transactionManager"/> 
<bean class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" id="entityManagerFactory"> 
    <property name="dataSource" ref="dataSource"/> 
</bean> 

任何帮助将高度赞赏。谢谢！

Answer 1

使用ROO和maven pom解决了此问题。关于如何使用Ant构建的信息太少。

Answer 2

考虑到切换到Roo不是一个真正的解决方案，而是一种解决方法，我想分享我对这个问题的经验。

有你需要检查两件事情：

1. 你需要通过AspectJ进行编译的类。 Maven aspectj插件提供了这个要求。
2. 实体类必须用@Configurable

Answer 3

来注释我找到了解决办法：

这是正确的iajc任务

<iajc source ="1.6" target="1.6" sourceroots="src/main/java" destDir="src/main/webapp/WEB-INF/classes" showweaveinfo="true" verbose="true"> 
    <classpath> 
     <path refid="compile.classpath"/> 
     <path refid="aspectj.classpath"/> 
    </classpath> 
    <aspectpath> 
     <pathelement location="${workdir}/WEB-INF/lib/spring-aspects-3.2.6.RELEASE.jar" /> 
    </aspectpath> 
</iajc>
