Spring Boot 使用AOP切面实现后台日志管理模块

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维提供支持
• 日志记录尽可能减少性能影响

1.定义日志记录元注解

2.定义用于记录日志的实体类

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

/**

public class Log implements Serializable{
    private static final long serialVersionUID = 1L;

    private String logId;           //日志主键  
    private String type;            //日志类型  
    private String title;           //日志标题  
    private String remoteAddr;          //请求地址

    }


    public String getRequestUri() {

    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() {

        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;

工具类代码:

3.定义日志AOP切面类(日志新增及修改其它业务操作不做介绍):

}

属性文件中添加下列配置:

4.spring boot配置扫描切面，开启@AspectJ注解的支持

5.使用范例LoginController方法中添加日志注解

6.运行效果
