我正在尝试编写一个简单的Spring rest Web服务,因为我不熟悉maven(因为maven通常不能完成任务 - 连接问题),所以我现在正在尝试使用ant build。现在,构建正常,服务可以运行。但是如果触发持久性功能,它将提示:
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

我找到了解决方案:
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>

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

考虑到转换到Roo并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。
您需要检查两件事:
