报文格式转换工具：converter

功能描述：

可以把xml/json形式的数据根据自定义的模板来转换成为你想要的任何格式。

需要用到 freemarker 方面的知识。

示例

josn to json

1. 转换代码

   DataReader dataReader = new JsonDataReader();
   //读取数据
   dataReader.read("json 格式数据");
   //设置模板
   FreeMarkerFtl freeMarkerFtl = new FreeMarkerFtl();
   freeMarkerFtl.setTemplateName("模板名称");
   freeMarkerFtl.setTemplateText("模板数据");
   //转换结果
   String res = dataReader.converterFormat(freeMarkerFtl);

2. 模板

   {
     "uuid": "${uuid}",
     "p-sex": "${people.sex}",
     "p-name": "${people.name}",
     "list": [
   <#list people.people as obj>
       {
         "c-name": "${obj.name}",
         "c-age": "${obj.age}",
         "c-sex": "${obj.sex}"
       }<#if obj_has_next>,</#if>
   </#list>
     ]
   }

3. 数据

   {
     "uuid": "123456789032sdfgh",
     "people": {
       "sex": "男",
       "age": "20",
       "name": "王麻子",
       "people": [
         {
           "sex": "女",
           "age": "18",
           "name": "李傻子"
         },
         {
           "sex": "男",
           "age": "21",
           "name": "王大锤"
         }
       ]
     }
   }

4. 结果

   {
       "uuid":"123456789032sdfgh",
       "p-sex":"男",
       "p-name":"王麻子",
       "list":[
           {
               "c-name":"李傻子",
               "c-age":"18",
               "c-sex":"女"
           },
           {
               "c-name":"王大锤",
               "c-age":"21",
               "c-sex":"男"
           }
       ]
   }

json to xml

1. 只需要修改模板即可

   <?xml version="1.0" encoding="UTF-8" ?>
   <xml>
       <uuid>${uuid}</uuid>
       <p-sex>${people.sex}</p-sex>
       <p-name>${people.name}</p-name>
   <#list people.people as obj>
           <list>
               <c-name>${obj.name}</c-name>
               <c-age>${obj.age}</c-age>
               <c-sex>${obj.sex}</c-sex>
           </list>
   </#list>
   </xml>
   

xml to xml

1. 转换代码

   DataReader dataReader = new XmlDataReader();
   //读取数据
   dataReader.read("xml 格式数据");
   //设置模板
   FreeMarkerFtl freeMarkerFtl = new FreeMarkerFtl();
   freeMarkerFtl.setTemplateName("模板名称");
   freeMarkerFtl.setTemplateText("模板数据");
   //转换结果
   String res = dataReader.converterFormat(freeMarkerFtl);

2. 模板

   <xml>
       <uuid>${uuid}</uuid>
       <p-sex>${people.sex}</p-sex>
       <p-name>${people.name}</p-name>
   <#list people.people as obj>
           <list>
               <c-name>${obj.name}</c-name>
               <c-age>${obj.age}</c-age>
               <c-sex>${obj.sex}</c-sex>
           </list>
   </#list>
   </xml>

3. 数据

   <xml>
       <uuid>123456789032sdfgh</uuid>
       <people>
           <sex>男</sex>
           <age>20</age>
           <name>王麻子</name>
           <people>
               <sex>女</sex>
               <age>18</age>
               <name>李傻子</name>
           </people>
           <people>
               <sex>男</sex>
               <age>20</age>
               <name>王大锤</name>
           </people>
       </people>
   </xml>

4. 结果

   <?xml version="1.0" encoding="utf-8"?>
   
   <xml> 
     <uuid>123456789032sdfgh</uuid>  
     <p-sex>男</p-sex>  
     <p-name>王麻子</p-name>  
     <list> 
       <c-name>李傻子</c-name>  
       <c-age>18</c-age>  
       <c-sex>女</c-sex> 
     </list>  
     <list> 
       <c-name>王大锤</c-name>  
       <c-age>20</c-age>  
       <c-sex>男</c-sex> 
     </list>
   </xml>
   

xml to json

1. 修改模板即可

   {
     "uuid": "${uuid}",
     "p-sex": "${people.sex}",
     "p-name": "${people.name}",
     "list": [
   <#list people.people as obj>
       {
         "c-name": "${obj.name}",
         "c-age": "${obj.age}",
         "c-sex": "${obj.sex}"
       }<#if obj_has_next>,</#if>
   </#list>
     ]
   }
