无法读取JSON:字段名称输入意外结束

问题描述

我正在开发Spring MVC Web应用程序.我还没有开发UI.因此，我正在使用Advance Rest Client工具测试我的服务.

I am developing a Spring MVC web application. I am not still develop the UI. So I am testing my services using Advance Rest Client tool.

我的控制器

@Controller
@RequestMapping("/testController")
public class TestController {

@Autowired
private TestService testService;

@RequestMapping(value = "/test", method = RequestMethod.POST, consumes = { MediaType.APPLICATION_JSON_VALUE },  produces = { MediaType.APPLICATION_JSON_VALUE })
public
@ResponseBody void testMethod(@RequestBody TestParam testParam) {

    String tenant = testParam.getTenantCode();
    String testString = tenant + " is the tenant";
}
}

TestParam.java类

TestParam.java class

public class TestParam {

private String testVar;
private String tenantCode;

public String getTenantCode() {
    return tenantCode;
}

public void setTenantCode(String tenantCode) {
    this.tenantCode = tenantCode;
}

public String getTestVar() {
    return testVar;
}

public void setTestVar(String testVar) {
    this.testVar = testVar;
}
}

我使用Advance Rest Client和标头发送请求，并且请求链接已正确设置.

I send the request using Advance Rest Client and headers and request link has set correctly.

{"testVar":"Test","tenantCode":"DEMO"}

请求链接

http://localhost:8080/myApp/controller/testController/test

当TestParam具有一个veriable时，它可以正常工作.当它变成两个或两个以上时，它会给出错误，并且不会命中testMethod.

It works correctly when TestParam has one veriable. When it becomes two or more it gives an Error and it not hit the testMethod.

exception is com.fasterxml.jackson.core.JsonParseException:  Unexpected end-of-input in field name at [Source:org.apache.catalina.connector.CoyoteInputStream@7b24d498; line: 1, column: 43]

我去写了更多文章，但仍然找不到答案.

I went throw more articles and I still couldn't find the answer.
