您的Maven日志显示没有aspectj maven插件正在执行的迹象，因此没有编织。我假设您已将插件配置放入

我在aspect类中使用了注释：@Around（“execution（public filter.RolesFilter.doFilter（…）”）@Vaidy:您的答案没有意义。问题是关于编译时编织，但aop.xml仅用于加载时编织。@Battle\u Slug:Around建议的切入点语法是错误的。您不指定方法返回类型。因此，您应该会看到AspectJ编译器错误。例如，此语法是正确的：

@Around（“execution（public*filter.RolesFilter.doFilter（…）”

——请注意额外的

。包名可能仍然有问题，我不能不看你的代码。@kriegaex我添加了我的方面的代码。事实上，我没有任何错误。就像我的项目中没有AspectJ一样。我在方面类中使用了注释：@Around（“execution（public filter.RolesFilter.doFilter（…）”）@Vaidy:你的答案没有意义。问题是关于编译时编织，但aop.xml仅用于加载时编织。@Battle\u Slug:Around建议的切入点语法是错误的。您不指定方法返回类型。因此，您应该会看到AspectJ编译器错误。例如，此语法是正确的：
