设计原则和思路：
元注解方式结合AOP，灵活记录操作日志
能够记录详细错误日志为运营以及审计提供支持
日志记录尽可能减少性能影响
操作描述参数支持动态获取，其他参数自动记录。
1.定义日志记录元注解，
根据业务情况，要求description支持动态入参。例：新增应用{applicationName}，其中applicationName是请求参数名。
/**
* 自定义注解 拦截Controller
*
* @author jianggy
*
*/
@Target({ ElementType.PARAMETER, ElementType.METHOD })
@Retention(RetentionPolicy.RUNTIME)
public @interface SystemControllerLog {
/**
* 描述业务操作 例:Xxx管理-执行Xxx操作
* 支持动态入参，例：新增应用{applicationName}，其中applicationName是请求参数名
* @return
*/
String description() default "";
}
2.定义用于记录日志的实体类
package com.guahao.wcp.core.dal.dataobject;
import com.guahao.wcp.core.utils.StringUtils;
import java.io.Serializable;
import java.util.Date;
import java.util.Map;
/**
* 日志类-记录用户操作行为
*
* @author lin.r.x
*/
public class OperateLogDO extends BaseDO implements Serializable {
private static final long serialVersionUID = -4000845735266995243L;
private String userId; //用户ID
private String userName; //用户名
private String desc; //日志描述
private int isDeleted; //状态标识
private String menuName; //菜单名称
private String remoteAddr; //请求地址
private String requestUri; //URI
private String method; //请求方式
private String params; //提交参数
private String exception; //异常信息
private String type; //日志类型
public String getType() {
return StringUtils.isBlank(type) ? type : type.trim();
}
public void setType(String type) {
this.type = type;
}
public String getDesc() {
return StringUtils.isBlank(desc) ? desc : desc.trim();
}
public void setDesc(String desc) {
this.desc = desc;
}
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;
}
/**
* 设置请求参数
*
* @param paramMap
*/
public void setMapToParams(Map paramMap) {
if (paramMap == null) {
return;
}
StringBuilder params = new StringBuilder();
for (Map.Entry param : ((Map) 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 String getUserName() {
return StringUtils.isBlank(userName) ? userName : userName.trim();
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getUserId() {
return userId;
}
public void setUserId(String userId) {
this.userId = userId;
}
public String getMenuName() {
return menuName;
}
public void setMenuName(String menuName) {
this.menuName = menuName;
}
public int getIsDeleted() {
return isDeleted;
}
public void setIsDeleted(int isDeleted) {
this.isDeleted = isDeleted;
}
@Override
public String toString() {
return "OperateLogDO{" +
"userId='" + userId + '\'' +
", userName='" + userName + '\'' +
", desc='" + desc + '\'' +
", isDeleted=" + isDeleted +
", menuName='" + menuName + '\'' +
", remoteAddr='" + remoteAddr + '\'' +
", requestUri='" + requestUri + '\'' +
", method='" + method + '\'' +
", params='" + params + '\'' +
", exception='" + exception + '\'' +
", type='" + type + '\'' +
'}';
}
}
3.定义日志AOP切面类,通过logManager.insert(log)往数据库写入日志。
项目pom.xml中增加spring-boot-starter-aop
org.springframework.boot
spring-boot-starter-aop
具体的日志切点类实现
package com.guahao.wcp.gops.home.aop;

}
@Override
public void run() {
this.logManager.update(log);
}
}
}
4.实现AsyncConfigurer接口并重写AsyncConfigurer方法，并返回一个ThreadPoolTaskExecutor,这样我们就得到了一个基于线程池的TaskExecutor.
在Executor配置类中增加@EnableAsync注解，开启异步支持。
package com.guahao.wcp.gops.home.configuration;
import com.alibaba.dubbo.common.logger.Logger;
import com.alibaba.dubbo.common.logger.LoggerFactory;
import org.springframework.aop.interceptor.AsyncUncaughtExceptionHandler;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.AsyncConfigurer;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;
import java.lang.reflect.Method;
import java.util.concurrent.Executor;
/**
* @program: wcp
* @description: 配置类实现AsyncConfigurer接口并重写AsyncConfigurer方法，并返回一个ThreadPoolTaskExecutor
* @author: Cay.jiang
* @create: 2018-03-12 17:27
**/
//声明这是一个配置类
@Configuration
//开启注解：开启异步支持
@EnableAsync
public class TaskExecutorConfigurer implements AsyncConfigurer {
private static final Logger log = LoggerFactory.getLogger(TaskExecutorConfigurer.class);
@Bean
//配置类实现AsyncConfigurer接口并重写AsyncConfigurer方法，并返回一个ThreadPoolTaskExecutor
//这样我们就得到了一个基于线程池的TaskExecutor
@Override
public Executor getAsyncExecutor() {
ThreadPoolTaskExecutor taskExecutor = new ThreadPoolTaskExecutor();
//如果池中的实际线程数小于corePoolSize,无论是否其中有空闲的线程，都会给新的任务产生新的线程
taskExecutor.setCorePoolSize(5);
//连接池中保留的最大连接数。Default: 15 maxPoolSize
taskExecutor.setMaxPoolSize(10);
//线程池所使用的缓冲队列
taskExecutor.setQueueCapacity(25);
//等待所有线程执行完
taskExecutor.setWaitForTasksToCompleteOnShutdown(true);
taskExecutor.initialize();
return taskExecutor;
}
@Override
public AsyncUncaughtExceptionHandler getAsyncUncaughtExceptionHandler() {
return new WcpAsyncExceptionHandler();
}
/**
* 自定义异常处理类
* @author hry
*
*/
class WcpAsyncExceptionHandler implements AsyncUncaughtExceptionHandler {
//手动处理捕获的异常
@Override
public void handleUncaughtException(Throwable throwable, Method method, Object... obj) {
System.out.println("-------------》》》捕获到线程异常信息");
log.info("Exception message - " + throwable.getMessage());
log.info("Method name - " + method.getName());
for (Object param : obj) {
log.info("Parameter value - " + param);
}
}
}
}
5.logManager调用日志DAO操作，具体的mybatis实现就不写了。
package com.guahao.wcp.core.manager.operatelog.impl;
import com.guahao.wcp.core.dal.dataobject.OperateLogDO;
import com.guahao.wcp.core.dal.mapper.OperateLogMapper;
import com.guahao.wcp.core.manager.operatelog.LogManager;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service("logManager")
public class LogManagerImpl implements LogManager {
@Autowired
private OperateLogMapper operateLogDAO;
@Override
public int insert(OperateLogDO log) {
System.out.println("新增操作日志:"+log);
return operateLogDAO.insert(log);
}
@Override
public int update(OperateLogDO log) {
//暂不实现
//return this.logDao.updateByPrimaryKeySelective(log);
System.out.println("更新操作日志："+log);
return 1;
}
}
6.使用范例ApplicationController方法中添加日志注解
@RequestMapping(value = "/add.json", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8"})
@ResponseBody
@SystemControllerLog (description = "【应用管理】新增应用{applicationName}")
public BaseJson add(@ModelAttribute("application") ApplicationDO applicationDO, @ModelAttribute("team") TeamDO teamDO) {
.......
}
7.日志数据入库结果
8.日志结果展示，grafana配置，vue编写日志查询界面
