Java 实体类自动生成get set！

1.idea Ctrl+Alt+S 先配置上lombok插件，如图：

2.pom.xml中引入依赖，如图：

3.实体类上添加@Data，如图：

4.看.class文件，get set toString 方法都会有。

package com.example.domain;
    
    public class Users {
        private String id;
        private String name;
        private String age;
    
        public Users() {
        }
    
        public String getId() {
            return this.id;
        }
    
        public String getName() {
            return this.name;
        }
    
        public String getAge() {
            return this.age;
        }
    
        public void setId(String id) {
            this.id = id;
        }
    
        public void setName(String name) {
            this.name = name;
        }
    
        public void setAge(String age) {
            this.age = age;
        }
    
        public boolean equals(Object o) {
            if (o == this) {
                return true;
            } else if (!(o instanceof Users)) {
                return false;
            } else {
                Users other = (Users)o;
                if (!other.canEqual(this)) {
                    return false;
                } else {
                    label47: {
                        Object this$id = this.getId();
                        Object other$id = other.getId();
                        if (this$id == null) {
                            if (other$id == null) {
                                break label47;
                            }
                        } else if (this$id.equals(other$id)) {
                            break label47;
                        }
    
                        return false;
                    }
    
                    Object this$name = this.getName();
                    Object other$name = other.getName();
                    if (this$name == null) {
                        if (other$name != null) {
                            return false;
                        }
                    } else if (!this$name.equals(other$name)) {
                        return false;
                    }
    
                    Object this$age = this.getAge();
                    Object other$age = other.getAge();
                    if (this$age == null) {
                        if (other$age != null) {
                            return false;
                        }
                    } else if (!this$age.equals(other$age)) {
                        return false;
                    }
    
                    return true;
                }
            }
        }
    
        protected boolean canEqual(Object other) {
            return other instanceof Users;
        }
    
        public int hashCode() {
            int PRIME = true;
            int result = 1;
            Object $id = this.getId();
            int result = result * 59 + ($id == null ? 43 : $id.hashCode());
            Object $name = this.getName();

        }
    
        public String toString() {
            return "Users(id=" + this.getId() + ", name=" + this.getName() + ", age=" + this.getAge() + ")";
        }
    }
