java 操作日志 log

定义注解log

import java.lang.annotation.Documented;
import java.lang.annotation.ElementType;
import java.lang.annotation.Inherited;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;


@Target({ElementType.TYPE,ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Inherited 
/*
* 定义注解 log
* 注解中含有一个元素 description
* description 元素 有默认值 "no description"
*/ 
public @interface  Log {


public String description() default "no description"; 
}

配置操作日志拦截器

 <!-- 操作日志拦截器 -->
            <interceptor name="OperationLogInterceptor"
                class="类名">
            </interceptor>

操作日志类

import java.lang.reflect.Method;




import java.util.Map;


import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;


import org.apache.struts2.ServletActionContext;




import com.opensymphony.xwork2.Action;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionInvocation;

public class OperationLogInterceptor extends AbstractInterceptor {

System.out.println("操作日志开始启动..");
Class clazz = invocation.getAction().getClass();

}
// if (executeresult) {//0代表成功；1代表失败
// operateLog.setOperState(0);
// }else {
// operateLog.setOperState(1);
// }
//acton和method的名字不为空时运行存储
if(!"".equals(actionName)&&!"".equals(methodName)){
try {
operateLogService.save(operateLog);
} catch (Exception e) {
e.printStackTrace();
}
}
            
}else{
//退出
}
return Action.SUCCESS;
}

}

使用方式

@Log(description="系统模块")

如果是多个中间用|分隔

@Log(description="系统模块|模块|操作")
