使用jsonschema2pojo-maven-plugin 插件根据json文件生成代码

jsonschema2pojo 是一个不错的工具，可以帮助我们快速的根据json 文件生成pojo代码，提高开发效率，以下为简单的
使用maven 插件进行代码生成

使用maven 插件配置

json 文件

src/main/resources/schema 目录

user.json
{
  "firstName": "John",
  "lastName" : "doe",
  "age"      : 26,
  "address"  : {
    "streetAddress": "naist street",
    "city"         : "Nara",
    "postalCode"   : "630-0192"

      "type"  : "home",
      "number": "0123-4567-8910"
    }
  ]
}
app.json
{
  "appname": "John",
  "apptag" : "doe",
  "appdescribe"  : {
    "streetAddress": "naist street",
    "city"         : "Nara",
    "postalCode"   : "630-0192"

    {
      "type"  : "home",
      "number": "0123-4567-8910"
    }
  ]
}

生成代码

mvn  package

说明

jsonschema2pojo 功能比较强大，可以根据yaml xml 等文件格式生成pojo，同时可以方便的为我们生成代码，同时也比较灵活
在api 盛行的时代还是比较好的，同时swagger generator 也是一个不错的选择

生成结果
