AnnotationConfigApplicationContext尚未刷新 - 出了什么问题？ [英] AnnotationConfigApplicationContext has not been refreshed yet - what's wrong?

问题描述

我的非常基本的春天应用程序停止工作，我不明白发生了什么。
pom.xml：

My very basic spring application stopped working and I can't understand what's happened. pom.xml:

<properties>
    <spring.version>4.1.1.RELEASE</spring.version>
</properties>

<dependencies>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
        <version>${spring.version}</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>${spring.version}</version>
    </dependency>
</dependencies>

配置类别：

@Configuration
public class MyConfig {

@Bean
public HelloWorld helloWorld() {
         return new HelloWorld();
    }
}

Bean类： / p>

Bean class:

public class HelloWorld {
    private String message;

    public void setMessage(String message) {
        this.message = message;
    }
    public String getMessage() {
         return message;
    }
}

申请入境点：

public class MainApp {
public static void main(String[] args) {
    AnnotationConfigApplicationContext ctx = new AnnotationConfigApplicationContext();
    ctx.register(MyConfig.class);
    HelloWorld bean = ctx.getBean(HelloWorld.class);
    bean.setMessage("ladjfaj");
    System.out.println(bean.getMessage());
}
}

And I'm getting an error

线程main中的异常java.lang.IllegalStateException：org.springframework.context.annotation.AnnotationConfigApplicationContext@6ebf8cf5尚未刷新

推荐答案

ctx.refresh（）之前，您可以调用 ctx.getBean（HelloWorld.class）;
