我正在通过spring boot应用程序实现rest webservice .

application.properties
server.port=8082
server.contexPath=/services
logging.level.org.springframework.web = DEBUG
logging.level.com.myCompany= INFO
logging.file = ../logs/services.log
应用程序启动器类
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
调节器
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class AccountRestController {
private static final Logger logger = LoggerFactory.getLogger(AccountRestController.class);
@RequestMapping(value="/account", method=RequestMethod.GET)
public void createAccount(){
logger.info("ACCOUNT METHOD CALLED");
}
}
当我在浏览器中触发http://localhost:8082/services/account URL时,我在控制台中看到 Did not find handler method for [/services/account] 消息,如下所示
2018-02-06 08:30:42.868 DEBUG 7532 --- [http-nio-8082-exec-3] s.w.s.m.m.a.RequestMappingHandlerMapping : Looking up handler method for path /services/account

我没有看到消息 - 在控制台中调用ACCOUNT METHOD意味着控制器方法没有被调用 . 你能告诉我为什么createAccount()方法没被调用?
控制器类是否被Spring工厂识别/扫描?
导致此错误的原因是什么?

看起来你拼错了那个属性,它应该是server.contex t Path,而不是像你的情况那样的server.contexPath(没有't') .
请将
server.contexPath
更改为server.contextPath
.再试一次,它应该工作,因为没有额外的
config
或代码 .http://www.baeldung.com/spring-boot-application-configuration
您能帮助我们捕捉您的项目结构吗?
AccountRestController
应该在Application
的同一个包(或子包中) . 像这样:你检查过你的日志文件了吗?它有任何日志吗?
您的server.contexPath应该是server.contextPath . 你错过了contexPath中的T.
您的 class 没有请求映射 . 在 @RestController 之后,应该有 @RequestMapping("/services/*)
