日志 AOP 依赖注解类 切面类 aop的启动实列

aop的依赖: org.springframework.boot spring-boot-starter-aop 注解类: import java.lang.annotation.Documented; import java.lang.annotation.ElementType; import java.lang.annotation.Retention; import java.lang.annotation.RetentionPolicy; import java.lang.annotation.Target;

@Target(ElementType.METHOD) @Retention(RetentionPolicy.RUNTIME) @Documented public @interface LogAnno { //要执行的操作类型比如：添加,修改等 public String operationType() default ""; //要执行的具体操作比如：添加文件等 public String operationName() default ""; }

切面类: import java.lang.reflect.Method; import java.util.Date; import javax.servlet.http.HttpServletRequest; import org.aspectj.lang.ProceedingJoinPoint; import org.aspectj.lang.Signature; import org.aspectj.lang.annotation.Around; import org.aspectj.lang.annotation.Aspect; import org.aspectj.lang.reflect.MethodSignature; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; import org.springframework.web.bind.annotation.RequestMapping;

import com.sinosoft.security.dao.LoggerMapper; import com.sinosoft.security.po.Logger; import com.sinosoft.security.po.extend.UserExtend; @Component @Aspect //切面类 public class LogAspect { @Autowired private HttpServletRequest request; @Autowired private LoggerMapper loggerMapper; //环绕通知 包名 类名 方法名 参数 @Around("execution(* com.sinosoft.*.controller.*.*(..))") public Object around(ProceedingJoinPoint point) throws Throwable{ //参数是目标方法 try { String typeName=""; String locat=""; Signature signature = point.getSignature(); MethodSignature methodSignature = (MethodSignature)signature; //获取当前执行的方法 Method targetMethod = methodSignature.getMethod(); //获取当前用户信息 UserExtend eUser = (UserExtend) request.getSession().getAttribute("CURRENT_USER_INFO"); **//判断是否具有LogAnno注解** if (targetMethod.isAnnotationPresent(LogAnno.class)) { typeName=targetMethod.getAnnotation(LogAnno.class).operationType(); locat=targetMethod.getAnnotation(LogAnno.class).operationName(); **//实体类** Logger logger=new Logger(); logger.setCreateTime(new Date()); logger.setUserid(eUser.getId()); logger.setOrgid(eUser.getOrgid()); logger.setOpType(typeName); logger.setLocation(locat); loggerMapper.insertSelective(logger); } } catch (Exception e) { e.printStackTrace(); } return point.proceed(); //代理方法的返回值 } }

spring开启对aop的支持 controller实列: @RequestMapping(method = RequestMethod.POST,value = “updateOrganization”) @ResponseBody @LogAnno(operationType=“修改”,operationName=“修改日志”) public AjaxResult updateOrganization(Organization organizatio){ AjaxResult result = organizationService.updateOrganization(organizatio); return result; }
