Spring AOP實(shí)現(xiàn)后臺(tái)管理系統(tǒng)日志管理

元注解方式結(jié)合AOP，靈活記錄操作日志
能夠記錄詳細(xì)錯(cuò)誤日志為運(yùn)維提供支持
日志記錄盡可能減少性能影響

1.定義日志記錄元注解

package com.myron.ims.annotation;

import java.lang.annotation.*;

/**
 * 自定義注解 攔截Controller
 * 
 * @author lin.r.x
 *
 */
@Target({ ElementType.PARAMETER, ElementType.METHOD })
@Retention(RetentionPolicy.RUNTIME)
public @interface SystemControllerLog {
    /**
     * 描述業(yè)務(wù)操作 例:Xxx管理-執(zhí)行Xxx操作
     * @return
     */
    String description() default "";
}

2.定義用于記錄日志的實(shí)體類

package com.myron.ims.bean;

import java.io.Serializable;
import com.myron.common.util.StringUtils;
import com.myron.common.util.UuidUtils;
import com.fasterxml.jackson.annotation.JsonFormat;
import java.util.Date;
import java.util.Map;

/**
 * 日志類-記錄用戶操作行為
 * @author lin.r.x
 *
 */
public class Log implements Serializable{
    private static final long serialVersionUID = 1L;

    private String logId;           //日志主鍵  
    private String type;            //日志類型  
    private String title;           //日志標(biāo)題  
    private String remoteAddr;          //請(qǐng)求地址  
    private String requestUri;          //URI   
    private String method;          //請(qǐng)求方式  
    private String params;          //提交參數(shù)  
    private String exception;           //異常    
    @JsonFormat(pattern="yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")
    private Date operateDate;           //開始時(shí)間  
    private String timeout;         //結(jié)束時(shí)間  
    private String userId;          //用戶ID  

    public String getLogId() {
        return StringUtils.isBlank(logId) ? logId : logId.trim();
    }
    public void setLogId(String logId) {
        this.logId = logId;
    }


    public String getType() {
        return StringUtils.isBlank(type) ? type : type.trim();
    }
    public void setType(String type) {
        this.type = type;
    }


    public String getTitle() {
        return StringUtils.isBlank(title) ? title : title.trim();
    }
    public void setTitle(String title) {
        this.title = title;
    }


    public String getRemoteAddr() {
        return StringUtils.isBlank(remoteAddr) ? remoteAddr : remoteAddr.trim();
    }
    public void setRemoteAddr(String remoteAddr) {
        this.remoteAddr = remoteAddr;
    }


    public String getRequestUri() {
        return StringUtils.isBlank(requestUri) ? requestUri : requestUri.trim();
    }
    public void setRequestUri(String requestUri) {
        this.requestUri = requestUri;
    }


    public String getMethod() {
        return StringUtils.isBlank(method) ? method : method.trim();
    }
    public void setMethod(String method) {
        this.method = method;
    }


    public String getParams() {
        return StringUtils.isBlank(params) ? params : params.trim();
    }
    public void setParams(String params) {
        this.params = params;
    }

    /**
     * 設(shè)置請(qǐng)求參數(shù)
     * @param paramMap
     */
    public void setMapToParams(Map<String, String[]> paramMap) {
        if (paramMap == null){
            return;
        }
        StringBuilder params = new StringBuilder();
        for (Map.Entry<String, String[]> param : ((Map<String, String[]>)paramMap).entrySet()){
            params.append(("".equals(params.toString()) ? "" : "&") + param.getKey() + "=");
            String paramValue = (param.getValue() != null && param.getValue().length > 0 ? param.getValue()[0] : "");
            params.append(StringUtils.abbr(StringUtils.endsWithIgnoreCase(param.getKey(), "password") ? "" : paramValue, 100));
        }
        this.params = params.toString();
    }


    public String getException() {
        return StringUtils.isBlank(exception) ? exception : exception.trim();
    }
    public void setException(String exception) {
        this.exception = exception;
    }


    public Date getOperateDate() {
        return operateDate;
    }
    public void setOperateDate(Date operateDate) {
        this.operateDate = operateDate;
    }


    public String getTimeout() {
        return StringUtils.isBlank(timeout) ? timeout : timeout.trim();
    }
    public void setTimeout(String timeout) {
        this.timeout = timeout;
    }


    public String getUserId() {
        return StringUtils.isBlank(userId) ? userId : userId.trim();
    }
    public void setUserId(String userId) {
        this.userId = userId;
    }

}

           try {

           } catch (Exception e) {
               e.printStackTrace();
           }    
           // 打印JVM信息。
           long beginTime = beginTimeThreadLocal.get().getTime();//得到線程綁定的局部變量（開始時(shí)間）

       @Override
       public void run() {
           this.logService.updateLog(log);
       }
   }
}

4.spring 配置掃描切面，開啟@AspectJ注解的支持

···

<aop:aspectj-autoproxy/>

<context:component-scan base-package="com.myron.ims.aop" />
<context:component-scan base-package="com.myron.ims.service"/>

<bean id="taskExecutor"   class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor">  
    <property name="corePoolSize" value="5" />  
    <property name="maxPoolSize" value="10" />  
    <property name="WaitForTasksToCompleteOnShutdown" value="true" />  
</bean>

···

5.使用范例LoginController方法中添加日志注解

···
/**
*系統(tǒng)登入
*/
@RequestMapping("/login.do")
@SystemControllerLog(description="登入系統(tǒng)")
@ResponseBody
public Map<String, Object> login(String username, String password, Boolean rememberMe, HttpServletRequest req){
//業(yè)務(wù)代碼省略...
}

/**
 * 安全退出登入
 * @return
 */
@SystemControllerLog(description="安全退出系統(tǒng)")
@RequestMapping("logout.do")
public String logout(){
    Subject subject=SecurityUtils.getSubject();
    if(subject.isAuthenticated()){
        subject.logout(); // session 會(huì)銷毀，在SessionListener監(jiān)聽session銷毀，清理權(quán)限緩存
    }
    return "/login.jsp";
}

6.運(yùn)行效果
