fastjson对象转map

FastJson提供了将Java对象转换为Map的方法。可以使用FastJson的`toJSONString`方法将对象转换为JSON字符串，然后使用`parseObject`方法将JSON字符串转换为Map。具体代码如下：

User user = new User();
user.setName("校长");
user.setAge(3);
user.setSalary(new BigDecimal("123456789.0123"));

// 对象转换为Map
String jsonString = JSON.toJSONString(user); // 将对象转换为JSON字符串
Map<String, Object> map = JSON.parseObject(jsonString, new TypeReference<Map<String, Object>>(){});

System.out.println("map = " + map); // 输出转换后的Map

以上代码将对象`user`转换为JSON字符串`jsonString`，然后使用`parseObject`方法将JSON字符串转换为Map对象`map`。最后打印输出转换后的Map。

注意：需要导入FastJson的相关依赖，并引入FastJson的包进行转换。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
