我有一个用于 Rest 服务的 Spring Controller :
@Controller
@RequestMapping(value = "/sample")
public class SampleController
{
@RequestMapping(value = "/getText", method = RequestMethod.GET, produces = "text/plain")
@ResponseBody
public String testMethod(@RequestParam("locale") final String locale) {
return "Hello Worlds TEXT";
}
}
当我在 https://localhost:9002/sample/getText?locale=en 执行 GET 请求时，我会收到错误“无法找到可接受的表示”。但我需要一个纯文本。您能解释一下我如何获得简单的文本吗？
"Could not find acceptable representation" using spring-boot-starter-web没有解决我的问题
我有堆栈跟踪:

最佳答案
嘿，你的代码工作正常。我也尝试过同样的。请参阅下面的代码。请确保您发送的获取请求正确。
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
@RequestMapping(value = "/sample")
public class SampleController {
@RequestMapping(value = "/getText", method = RequestMethod.GET, produces = "text/plain")
@ResponseBody
public String testMethod(@RequestParam("locale") final String locale) {
return "Hello Worlds TEXT";
}
}
请查看浏览器的请求响应屏幕截图。
