ssm springaop 自定义注解加日志数据到数据库

弄得过程中出现过好多问题。（报错时候切入方法不正常执行，）

1、需要导的包：slf4j-log4j12-1.6.2.jar slf4j-api-1.6.2.jar （这两个jar包版本最好保持一致，之前我使用不同版本报错）

aspectjweaver-1.6.8_2.jar log4j-1.2.15.jar aopalliance-1.0.jar

2、新建一个log.java 自定义注解类

package com.user.sessionFilter;
import java.lang.annotation.*;
//https://blog.csdn.net/erlian1992/article/details/53402519
//自定义注解相关知识参考上面链接
@Target({ElementType.PARAMETER, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface Log {
//自定义注解
/** 要执行的操作类型比如：add操作 **/
public String operationType() default "";

/** 要执行的具体操作比如：添加用户 **/
public String operationName() default "";

}

3、新建一个SystemLogAspect .java

执行顺序如下：

//正常 device : -->around-->before-->method-->after-->afterReturn

//报错 device : -->around-->before-->method-->after-->afterthrowing

package com.user.sessionFilter;
import java.lang.reflect.Method;

String params = "";
if (joinPoint.getArgs() != null && joinPoint.getArgs().length > 0) {

}
/*==========记录本地异常日志==========*/
logger.error("异常方法:{}异常代码:{}异常信息:{}参数:{}", joinPoint.getTarget().getClass().getName() + joinPoint.getSignature().getName());

}

}

4、controller ---》service

  @Controller
@RequestMapping("SystemLog")
public class AopController {

@Autowired
private AopService userService;

@RequestMapping("testAOP")
// @Log(operationType="addOperation:",operationName="添加用户")
public ModelAndView testAOP( HttpServletRequest request, HttpServletResponse response,Model model){
String success ="0";
try {
User user =new User();
user.setName("sy");
user.setPsd("22");
success= userService.insertUser(user);
System.out.println("dsdsdsdsdsdsdsdsdsdsdsdsdsdsdsdsdsd");
} catch (Exception e) {
success="0";
}
if("0".equals(success)){
return new ModelAndView("user/aopFail");
}
return new ModelAndView("user/aopSuccess");

}

service:(具体切入方法在此)

operationType与operationName和log.java中定义的一致

@Log(operationType="addOperation:",operationName="添加用户正常")

public String insertUser(User user){
iUserMapper.insertUser(user);
return "1";
}

5、springMvc.xml配置红色为配置

<context:component-scan base-package="com.user" >

</context:component-scan>
<aop:aspectj-autoproxy />


<!--开启aopproxy-target-class="true"默认是false,更改为true时使用的是cglib动态代理,这样只能实现对Controller层的日志记录
proxy-target-class等于true是强制使用cglib代理，proxy-target-class默认是false，如果你的类实现了接口就走JDK代理，如果没有，走cglib代理
注：对于单利模式建议使用cglib代理，虽然JDK动态代理比cglib代理速度快，但性能不如cglib

6、最后附上表

CREATE TABLE `systemlog` (
`id` int(20) NOT NULL auto_increment,
`description` varchar(100) default NULL,
`method` varchar(100) default NULL,
`requestIp` varchar(100) default NULL,
`exceptioncode` varchar(100) default NULL,
`exceptionDetail` varchar(100) default NULL,
`params` varchar(100) default NULL,
`createBy` varchar(100) default NULL,
`createDate` timestamp NULL default NULL COMMENT '系统日志',
PRIMARY KEY (`id`),
KEY `id` (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8
