170807、intellij idea maven集成lombok实例

简介： lombok 通过简单注解方式简化java代码。（如消除实体对象的get/setter方法、日志对象声明等...）

安装步骤：

1、选择支持注解处理：Settings-->Build-->Annotation Processors-->勾选上Enable annotation processing

2、安装插件：Settings-->Plugins-->单击Browse repositories

查找lombok插件并进行安装：

3、新增lombok maven jar包依赖：

　<!--日志封装类-->
<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
</dependency>

4、新增lombok maven插件支持：

<plugin>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.16.14</version>
</plugin>

使用lombok案例

未使用lombok代码：

import java.io.Serializable;
import java.util.Date;

public class UserBean  implements Serializable {
    private static final long serialVersionUID = -3083532522233597386L;

    private String userId;

    private String userName;

    private String password;

    private Date birthDay;

    private String mobile;

    private String email;

    private Date createdDate;

    public String getUserId() {
        return userId;
    }

    public void setUserId(String userId) {
        this.userId = userId;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public Date getBirthDay() {
        return birthDay;
    }

    public void setBirthDay(Date birthDay) {
        this.birthDay = birthDay;
    }

    public String getMobile() {
        return mobile;
    }

    public void setMobile(String mobile) {
        this.mobile = mobile;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public Date getCreatedDate() {
        return createdDate;
    }

    public void setCreatedDate(Date createdDate) {
        this.createdDate = createdDate;
    }
}

使用lombok后的代码：

import lombok.Data;
import java.io.Serializable;
import java.util.Date;

@Data
public class UserBean  implements Serializable {
    private static final long serialVersionUID = -3083532522233597386L;

    private String userId;

    private String userName;

    private String password;

    private Date birthDay;

    private String mobile;

    private String email;

    private Date createdDate;

}

日志使用
1、在类上增加注解@Slf4j
2、方法体中直接用使用log
