1. List集合转换成json代码
List list = new ArrayList();
list.add( "first" );
list.add( "second" );
JSONArray jsonArray2 = JSONArray.fromObject( list );
2. Map集合转换成json代码
Map map = new HashMap();
map.put("name", "json");
map.put("bool", Boolean.TRUE);
map.put("int", new Integer(1));
map.put("arr", new String[] { "a", "b" });
map.put("func", "function(i){ return this.arr[i]; }");
JSONObject json = JSONObject.fromObject(map);
3. Bean转换成json代码
JSONObject jsonObject = JSONObject.fromObject(new JsonBean());
4. 数组转换成json代码
boolean[] boolArray = new boolean[] { true, false, true };
JSONArray jsonArray1 = JSONArray.fromObject(boolArray);
5. 一般数据转换成json代码
JSONArray jsonArray3 = JSONArray.fromObject("[‘json‘,‘is‘,‘easy‘]" );
List<Role> roleList = roleService.selectRole(conditions);
if(roleList.size()>0)
{
Role role = roleList.get(0);
role.setAddOrEdit("update");
result = JSONObject.fromObject(role);
}
return : {addOrEdit: "update", createBy: "admin", createDate: {…}, roleId: "SALES_55b1dcd69aa64be6845bafef1e04707a", roleName: "test1", …}
