本文解析了在使用SpringMVC开发RESTful服务时，遇到的关于视图解析异常的具体原因及三种解决方案，包括修改URL、添加@ResponseBody注解及调整默认ContentType。

最近使用spring mvc开发项目，遇到一个问题：

javax.servlet.ServletException: Could not resolve view with name 'ok' in servlet with name 'spring'

引起该异常的原因：在mvc的配置文件中配置了：

<property name="defaultContentType" value="text/html" />

而url(http://localhost:8080/SpringRestful/services/User/users?_method=delete)

请求没有带扩展名，且请求的方法没有@ResponseBody签名，spring会认为你请求的结果是一个html的视图，所以才抛出了上面的异常。

解决方法如下任意一种：

1.url请求加上扩展名：

http://localhost:8080/SpringRestful/services/User/users.json?_method=delete

2.请求的方法上加上@ResponseBody签名

<property name="defaultContentType" value="text/html" />改为<property name="defaultContentType" value="application/json" />
