自定义注解实现日志功能

介绍：现在做的项目，需要通过aop实现添加日志功能，在需要的方法上加注解即可对该方法执行拦截并添加日志

1.      添加相关依赖

<spring.version>4.1.7.RELEASE</spring.version>
<aspectj.version>1.6.8</aspectj.version>
<!—springaop相关—>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-expression</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-orm</artifactId>
<version>${spring.version}</version>

<version>${aspectj.version}</version>
</dependency>
<dependency>
<groupId>aopalliance</groupId>
<artifactId>aopalliance</artifactId>
<version>1.0</version>
</dependency>

2.编写自定义注解类

package com.sen.log;

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;

@Target({ElementType.PARAMETER, ElementType.METHOD}) 
@Retention(RetentionPolicy.RUNTIME) 
@Documented 
public @interface Log {

	/**方法描述*/
	public String  methodDesc() default "";

}

3.编写日志实体类，用于保存到数据库

package com.sen.pojo;

import java.util.Date;

/**
 * ClassName: SystemLog
 * 
 * @Description: 日志实体类
 * @author shaosen
 * @date 2018年5月9日
 */
public class SystemLog {

	/**唯一标识*/
	private String id;
	/**方法描述*/
	private String description;
	/**方法名*/
	private String method;
	/**请求ip*/
	private String requestIp;
	/**异常code*/
	private String exceptioncode;
	/**异常描述*/
	private String exceptionDetail;
	/**创建日期*/
	private Date createDate;
	/**请求参数*/
	private String params;

	public String getParams() {
		return params;
	}

	public void setParams(String params) {
		this.params = params;
	}

	public String getId() {
		return id;
	}

	public void setId(String id) {
		this.id = id;
	}

	public String getDescription() {
		return description;
	}

	public void setDescription(String description) {
		this.description = description;
	}

	public String getMethod() {
		return method;
	}

	public void setMethod(String method) {
		this.method = method;
	}

	public String getRequestIp() {
		return requestIp;
	}

	public void setRequestIp(String requestIp) {
		this.requestIp = requestIp;
	}

	public String getExceptioncode() {
		return exceptioncode;
	}

	public void setExceptioncode(String exceptioncode) {
		this.exceptioncode = exceptioncode;
	}

	public String getExceptionDetail() {
		return exceptionDetail;
	}

	public void setExceptionDetail(String exceptionDetail) {
		this.exceptionDetail = exceptionDetail;
	}


	public Date getCreateDate() {
		return createDate;
	}

	public void setCreateDate(Date createDate) {
		this.createDate = createDate;
	}

	@Override
	public String toString() {
		return "SystemLog [id=" + id + ", description=" + description + ", method=" &#
