no String-argument constructor/factory method to deserialize from String value ('2')

这个错误信息表示在解析JSON时出现了问题，无法构造一个没有String参数的构造函数或工厂方法来从字符串值('2')中反序列化。 根据引用中的描述，可能是由于在定义变量时类型不一致导致的，前端传递的JSON中的变量名为content，类型为string，但在后端定义中将其定义为Content类型。这样的定义不符合要求，因此需要对定义进行修改以匹配前端传递的数据类型。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
