利用spring切面编程特性 实现监控controller操作,利用反射自动拿到方法参数以及返回值的名,类型以及值,记录持久化
框架:JEECG JDK:1.8
1. 首先第一步建立一个自定义
annotation
SystemLog
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;
/***
*
*
* Title: SystemLog<br/>
*
* Description: 日志记录<br/>
*
* @author 王维杰
*
* @date 2018年4月2日
*/
@Target({ ElementType.PARAMETER, ElementType.METHOD })
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface SystemLog {
/***
*
* @Title: methodsDescription
* @Description: 方法描述
* @return String 返回类型
* @throws
*/
String methodsDescription() default "";
}
2. 书写拦截类

List<Map<String, Object>> map_list = new ArrayList<Map<String, Object>>();

} catch (Exception e) {

}

}
}
3. 给出log实体
LogEntity
我这边是使用JEECG框架根据数据库表生成的实体 具体的get set方法就不再赘述
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
import org.hibernate.annotations.GenericGenerator;
import org.jeecgframework.poi.excel.annotation.Excel;
/**
*
* @ClassName: LogEntity
* @Description:
* @author 王维杰
* @date 2018年4月3日
*
*/
public class LogEntity{
/** 日志id */
private java.lang.String id;
/** 操作用户id */
private java.lang.String userId;
/** 操作用户名 */
private java.lang.String loginAccount;
/** 操作人ip */
private java.lang.String loginIp;
/** 操作请求的链接 */
private java.lang.String actionUrl;
/** 方法描述 */
private java.lang.String methodsDescrip;
/** 方法名 */
private java.lang.String methods;
/** 返回值 */
private java.lang.String result;
/** actionTime */
private java.util.Date actionTime;
/** 本次执行描述 */
private java.lang.String description;
/** 本次执行时间 */
private java.util.Date gmtcreate;
/** 该操作状态,1表示成功,-1表示失败! */
private java.lang.Integer state;
/** 不为空的参数列表 */
private java.lang.String paramList;
/** 操作级别 */
private java.lang.Integer operationLevel;
/** 本条记录创建时间 */
private java.util.Date careatTime;
3. 修改配置文件
spring-mvc.xml
以及spring-mvc-hibernate.xml
让JEECG
框架知道日志系统的位置
spring-mvc.xml文件,增加aop上下文 仔细看看有没漏下的
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-3.0.xsd ">
<!-- 启用切面注解 -->
<aop:aspectj-autoproxy proxy-target-class="true" />
<!-- 增加aop自动扫描并实例化bean -->
<bean id="logAopAction" class="切面类全路径"></bean>
如果需要持久化,打开
spring-mvc-hibernate.xml
文件,增加一个<value>持久层包路径</value>
最后用法 直接在需要记录日志的方法名上 书写:
@SystemLog(methodsDescription="方法描述")
搞定
