Micronaut HelloWorld错误：意外错误：非法名称。$ HelloControllerDefinition

Question

尝试在演示代码上进行操作 https://docs.micronaut.io/latest/guide/index.html#creatingServer

执行以下步骤： src / main / java / example / helloworld / HelloController.java

出现了错误：

> Task :compileJava FAILED
Note: Creating bean classes for 1 type elements
error: Unexpected error: Illegal name .$HelloControllerDefinition
1 error

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':compileJava'.
> Compilation failed; see the compiler error output for details.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

BUILD FAILED in 7s
1 actionable task: 1 executed

我知道还有另一个与此相关的问题，但没有答案 error: Unexpected error: Illegal name .$HelloControllerDefinition

我该怎么办？

，而hellocontroller正是文档所遵循的

import io.micronaut.http.annotation.*;

@Controller("/hello") 
public class HelloController {
    @Get 
    public String index() {
        return "Hello World"; 
    }
}

Answer 1

HelloController需要定义为位于程序包中。如果您完全按照指南进行操作，请尝试以下操作，

package example.helloworld;

import io.micronaut.http.annotation.*;

@Controller("/hello") 
public class HelloController {
    @Get 
    public String index() {
        return "Hello World"; 
    }
}
