我正在根据应用程序属性文件中存在的切入点的数量创建aspectjexpressionpointcutadvisor。它正在创建没有错误的对象,但是切入点没有被触发。
**注意:**需要根据属性文件中的切入点表达式的数量动态创建bean(不同)。
应用程序属性文件
pointcut.expression.projectUpdate[0]= execution(* com.abc.app.service.impl.TestServiceImpl.updateProjectDetails(..))
pointcut.expression.projectUpdate[1]= execution(* com.abc.app.service.impl.TestServiceImpl.cancelProject(..))
pointcut.expression.projectUpdate[2]= execution(* com.abc.app.service.impl.TestCSATRatingServiceImpl.saveRatingDetails(..))
testconfig.class类
@Configuration
public class TestConfig implements BeanFactoryAware {
@Autowired
private PointcutExprProperties pcExprProp;
@Autowired(required=false)
private ProjectUpdateAspect projectUpdateAdvice;
private BeanFactory beanFactory;
@Override
public void setBeanFactory(BeanFactory beanFactory) {
this.beanFactory = beanFactory;
}
@PostConstruct
public void configure() {
ConfigurableBeanFactory configurableBeanFactory = (ConfigurableBeanFactory) beanFactory;
int i=1;
for(String pointCut : pcExprProp.getProjectUpdate()) {
AspectJExpressionPointcutAdvisor projectUpdateAdvisor = new AspectJExpressionPointcutAdvisor();
projectUpdateAdvisor.setExpression(pointCut);
projectUpdateAdvisor.setAdvice(projectUpdateAdvice);
configurableBeanFactory.registerSingleton("beanName_"+i, projectUpdateAdvisor);
i++;
}
}
}
projectupdateaspect.class类
@Component
@Aspect
public class ProjectUpdateAspect implements AfterReturningAdvice {
private static final Logger log = LoggerFactory.getLogger(ProjectUpdateAspect.class);
@Override
public void afterReturning(Object returnValue, Method method, Object[] args, Object target) throws Throwable {
try {
// some thing
}catch (Exception exception) {
log.error("Error while processing ProjectUpdateAspect",exception);
}
}
}
PointCutExpr属性
@Configuration
@ConfigurationProperties(prefix = "pointcut.expression")
@Validated
public class PointcutExprProperties {
@NotNull
private List<String> projectCreate;
@NotNull
private List<String> projectUpdate;
public List<String> getProjectCreate() {
return projectCreate;
}
public void setProjectCreate(List<String> projectCreate) {
this.projectCreate = projectCreate;
}
public List<String> getProjectUpdate() {
return projectUpdate;
}
public void setProjectUpdate(List<String> projectUpdate) {
this.projectUpdate = projectUpdate;
}
}
请告诉我如何解决这个问题。

我建议你这样做:
你没有把你的“方面”定义为
@Component @Aspect
但要让它实现MethodInterceptor
.你创造了
AspectJExpressionPointcut
属性文件中的值。你注册了一个
DefaultPointcutAdvisor
(使用切入点和拦截器配置)作为bean。另请参阅我的答案(更新3)和我刚刚为您更新的github示例存储库,以便包括从中读取切入点
application.properties
.
