Micronaut 控制器错误页面未找到 [英] Micronaut controller error Page Not Found

问题描述

我创建了一个新的 micronaut 应用程序mn create-app example.micronaut.complete

I created a new micronaut app using mn create-app example.micronaut.complete

之后，我使用intellij打开了项目，并使用以下代码向项目添加了一个新类作为TestController:

After that I opened the project using intellij and added a new class as TestController to the project with code below:

package example.micronaut;
import io.micronaut.http.MediaType;
import io.micronaut.http.annotation.Controller;
import io.micronaut.http.annotation.Get;


@Controller("/hello")
public class TestController {

TestController(){}

@Get(value = "/", produces = MediaType.TEXT_PLAIN)
String getTest(){
    return "some string";
   }
}

但是我得到了

{"_links":{"self":{"href":"/","templated":false}},"message":"Page Not Found"}

每当我尝试访问/hello 端点

whenever I try to access the /hello end point

我的 application.yml 如下所示:

My application.yml looks like this:

micronaut:
    application:
        name: complete
    server:
        port: 8080

推荐答案

如果没有更多地了解您的项目，就很难说出哪里出了问题.我已将您的代码直接粘贴到一个项目中，它按预期工作.请参阅 https://github.com/jeffbrown/khwaja404 上的项目.https://github.com/jeffbrown/khwaja404/blob/a3e57623ed5b30e28eb95bfe0f4a4a5c9d123fd8/src/main/java/example/micronaut/TestController.java 工作正常...

Without seeing more of your project it is hard to say what is wrong. I have pasted your code directly into a project and it works as expected. See the project at https://github.com/jeffbrown/khwaja404. The controller at https://github.com/jeffbrown/khwaja404/blob/a3e57623ed5b30e28eb95bfe0f4a4a5c9d123fd8/src/main/java/example/micronaut/TestController.java works fine...

package example.micronaut;

import io.micronaut.http.MediaType;
import io.micronaut.http.annotation.Controller;
import io.micronaut.http.annotation.Get;


@Controller("/hello")
public class TestController {

    // this empty constructor is not
    // needed, but isn't a problem...
    TestController() {
    }

    @Get(value = "/", produces = MediaType.TEXT_PLAIN)
    String getTest() {
        return "some string";
    }
}

端点响应:

$ curl http://localhost:8080/hello
some string

需要注意的一件事是您可能缺少 micronaut-inject-java 和/或 micronaut-inject 依赖项，如 https://github.com/jeffbrown/khwaja403204040404b304b304b30404b304b3040404040404b304b304040404b304b3040404b30404040404b3040404b30404b30404b304b30404b304040404040404004004004004000000000000000000000000000000000000000000000000000000000000000000L29.

One thing to look for is you may be missing the micronaut-inject-java and/or micronaut-inject dependency as expressed at https://github.com/jeffbrown/khwaja404/blob/a3e57623ed5b30e28eb95bfe0f4a4a5c9d123fd8/build.gradle#L27-L29.

另一个是，如果您从 IDE(如 IntelliJ IDEA)运行应用程序，请确保在构建中启用了注释处理器.

Another is if you are running the app from the IDE (like IntelliJ IDEA), make sure you have annotation processors enabled in the build.
