我通过 XML 启用加载时间编织

<aop:aspectj-autoproxy proxy-target-class="true"/>
<context:load-time-weaver aspectj-weaving="on" />

相关依赖如下：

        spring-orm = 4.0.x;
        spring-aop = 4.0.x;
        spring-tx = 4.0.x;
        spring-instrument = 4.0.x;
        aspectjweaver = 1.8.x;

我也在使用 Spring Instrument Java Agent 启动 JVM

-javaagent:spring-instrument-4.0.7.RELEASE.jar

而且我不断收到 NullPointerException （请参阅下面的异常）

我还尝试通过 Java 配置启用，但这也无济于事。
