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", …}
