我有一个示例 spring rest mvc 应用程序，它具有以下 java 代码:
示例 Controller .java
import org.apache.logging.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.util.StringUtils;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
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;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("sample")
public class SampleController {
@RequestMapping(method = RequestMethod.GET, produces = "application/json")
@ResponseBody
public String getBatches()//@RequestParam(name = "name", required = true) String name)
{
return "Hello ";
}
}

主页为我提供了 apache 页面，但一旦我尝试访问 127.0.0.1:8080/sample，它就会抛出 404 错误。日志都对此保持沉默。不确定如何解决这个问题。
最佳答案
在
中放置一个断点org.springframework.web.servlet.mvc.condition.PatternsRequestCondition.getMatchingPattern(String pattern, String lookupPath).
您会明白为什么您的请求没有匹配项。
关于java - 如何调试在 spring mvc rest 中找不到的 404 资源？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/33887618/
