最近在做自己的web项目的时候,搭建完ssm打算跑一下,结果出现了 java.lang.IllegalArgumentException: No converter found for return value of type: class java.util的错误.
控制层部分用的是@ResposeBody,方法返回Object类型参数,不出现错误的情况下应该在前台接收到的是转换后的json格式数据.出现错误后,检查了一下Maven的pom.xml,发现仓库中没有引入json的相关依赖,也就是json的依赖包没有,所以出现了上面所谓的转换失败的错误代码.
看到网上还有别的出现此错误代码的问题,是因为需要转换成json格式的对象的成员变量没有get方法.
