紧急！！求大神帮忙！Spring MVC使用@RequestBody 接收带空格的字符串，报错。

实体类：
public class TestVO {
private String CreateDate;

public String getCreateDate() {
    return CreateDate;
}

public void setCreateDate(String createDate) {
    CreateDate = createDate;
}
}

Controller：

@RequestMapping(value="/test2/", headers="Accept=application/json")
@ResponseBody
public TestVO test2(@RequestBody TestVO user) {

    return user;
}


使用CURL发送请求：
curl -H "Content-Type: application/json"  -d {\"createDate\":\"2015-07-31 00:00:00\"} --request POST http://localhost:8081/HQ520/test2/
报的错误：
八月 05, 2015 1:46:35 下午 org.apache.catalina.core.StandardWrapperValve invoke

严重: Servlet.service() for servlet [rest] in context with path [/HQ520] threw exception [Request processing failed; nested exception is org.springframework.http.converter.HttpMessageNotReadableException: Could not read JSON: Unexpected end-of-input in VALUE_STRING

我测试过了，应该是空格的问题，以下是我的单元测试

@Test
public void testInsertObject() throws Exception {

String url = URI + "/object";

TestVO anObject = new TestVO();
anObject.setCreateDate("2015-07-31 00:00:00");

Gson gson = new Gson();
String json = gson.toJson(anObject);

    MvcResult result = this.mockMvc.perform(MockMvcRequestBuilders.post(url).contentType(MediaType.APPLICATION_JSON)
        .content(json))
        .andDo(print())
        .andReturn();

}

这样会报错，如果改成nObject.setCreateDate("2015-07-31-00:00:00"); 就不会报错了

我认为应该是MappingJacksonHttpMessageConverter解析JSON字符串的时候，如果遇到空格就认为这个字符串结束，所以出现这个问题。

有哪位大神遇到过类似的问题？怎么解决？请指教。谢谢！

把你返回的字符串转为json字符串输出
