在线JSON转Java实体类(Bean/POJO/DTO)自动生成工具。支持深度嵌套JSON解析与List集合处理，一键生成标准Java代码。完美保留原JSON注释并自动生成 Getter/Setter 方法，大幅提高对接第三方API数据实体及构建Java数据模型的开发效率。
使用说明
功能介绍
1.支持解析嵌套 json 串, 根据递归进行解析嵌套对象
2.支持解析数组 json 串, 会取数组中第一个 json 串进行解析
3.检查 json 串格式是否正确, 输出错误的位置
4.生成注释
示例
解析嵌套 json 串
{
"name": "test", // 姓名
"age": 10, // 年齡
"addr": "四川成都", // 地址
"cls_info": [ // 班級
{
"name": "籃球班", // 班名
"teacher": "張老師" // 老師
},
{
"name": "美術班", // 班名
"teacher": "李老師" // 老師
}
]
}
处理后

package com.gotool.json2java;
import java.util.List;
public class ClsInfo {
private String name; // 班名
private String teacher; // 老師
public String getName() {
return this.name;
}
public void setName(String name) {
this.name = name;
}
public String getTeacher() {
return this.teacher;
}
public void setTeacher(String teacher) {
this.teacher = teacher;
}
}
public class GenerateObj {
private String name; // 姓名
private Integer age; // 年齡
private String addr; // 地址
private List<ClsInfo> cls_info; // 班級
public String getName() {
return this.name;
}
public void setName(String name) {
this.name = name;
}
public Integer getAge() {
return this.age;
}
public void setAge(Integer age) {
this.age = age;
}
public String getAddr() {
return this.addr;
}
public void setAddr(String addr) {
this.addr = addr;
}
public List<ClsInfo> getCls_info() {
return this.cls_info;
}
public void setCls_info(List<ClsInfo> cls_info) {
this.cls_info = cls_info;
}
}
直接解析数组 json 串
[
{
"name": "test",
"age": 10,
"addr": "四川成都",
"cls_info": [
{
"name": "篮球班",
"teacher": "张老师"
},
{
"name": "美术班",
"teacher": "李老师"
}
]
},
{
"name": "test2",
"age": 10,
"addr": "四川成都",
"cls_info": [
{
"name": "篮球班",
"teacher": "张老师"
},
{
"name": "美术班",
"teacher": "李老师"
}
]
}
]
