我非常基本的 spring 应用程序停止工作，我无法理解发生了什么。 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:

@Configuration
public class MyConfig {

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

Bean 类:

public class HelloWorld {
    private String message;

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

申请入口点:

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());
}
}

我得到一个错误

Exception in thread "main" java.lang.IllegalStateException: org.springframework.context.annotation.AnnotationConfigApplicationContext@6ebf8cf5 has not been refreshed yet at org.springframework.context.support.AbstractApplicationContext.assertBeanFactoryActive(AbstractApplicationContext.java:943) at org.springframework.context.support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:967) at com.nikolas.config.MainApp.main(MainApp.java:12)

最佳答案

您必须先调用 ctx.refresh()，然后才能调用 ctx.getBean(HelloWorld.class);

关于java - AnnotationConfigApplicationContext 尚未刷新 - 怎么了？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/28404817/
