eclipse - 如何在 Spring Boot 中使用 Bean 创建配置类？

Question

我正在将使用 spring jms 完成的项目转换为 spring boot 项目。我不知道如何将spring jms中的context.xml转换为spring boot中的配置类。我的context.xml如下

<bean
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

    <property name="location">
        <value>file:./config-env-receiver.properties</value>
    </property>
</bean>

<bean id="stepConnectionFactory" class="com.ibm.mq.jms.MQQueueConnectionFactory">
    <property name="hostName">
        <value>${mq.hostname.step}</value>
    </property>
    <property name="port">
        <value>${mq.port.step}</value>
    </property>
    <property name="channel">
        <value>${mq.channel.step}</value>
    </property>
    <property name="queueManager">
        <value>${mq.queuemanager.step}</value>
    </property>
    <property name="transportType">
        <value>1</value>
    </property>
</bean>

<bean id="jmsDestination" class="com.ibm.mq.jms.MQQueue">
    <constructor-arg value="${mq.queuename.step}" />
</bean>
<bean
    class="org.springframework.jms.listener.DefaultMessageListenerContainer">
    <property name="connectionFactory" ref="stepConnectionFactory" />
    <property name="sessionTransacted" value="true" />
    <property name="destinationName" value="${mq.queuename.step}" />
    <property name="exceptionListener" ref="exceptionListener" />
    <property name="messageListener" ref="stepOutListenerItemCreateUpdate" />
</bean>
<bean id="exceptionListener" class="com.message.view.CustomException">      
</bean>
    <bean id="stepOutListenerItemCreateUpdate"
    class="com.message.view.WMQueueMessageConsumer">
        </bean>
<bean id="springConnectionFactory"
    class="org.springframework.jms.connection.SingleConnectionFactory">
    <property name="targetConnectionFactory" ref="stepConnectionFactory" />
</bean>

<bean id="jmsTemplateStep" class="org.springframework.jms.core.JmsTemplate">
    <property name="connectionFactory" ref="springConnectionFactory" />
    <property name="defaultDestination" ref="jmsDestination" />
</bean>

<context:component-scan base-package="com.message.view">
</context:component-scan>

我尝试按如下方式创建 Application.class。

package hello;
import java.util.Arrays;
import javax.jms.JMSException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ImportResource;
import org.springframework.jms.connection.SingleConnectionFactory;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.listener.DefaultMessageListenerContainer;
import com.ibm.mq.jms.MQQueue;
import com.ibm.mq.jms.MQQueueConnectionFactory;

@SpringBootApplication
//@ImportResource("classpath:context_receiver.xml")
public class Application {

@Autowired
public CustomException customException;

@Autowired
public MessageListener messageListener;

@Bean
public MQQueueConnectionFactory getMQconnectionfactory(){
    MQQueueConnectionFactory mqconfactory=new MQQueueConnectionFactory();

    try {
        mqconfactory.setHostName("*******");
        mqconfactory.setPort(*****);
        mqconfactory.setChannel("**********");
        mqconfactory.setQueueManager("********");
        mqconfactory.setTransportType(1);
    } catch (JMSException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return mqconfactory;

}

@Bean
public MQQueue getMQQueue(){
    return new MQQueue();
} 



@Bean
public DefaultMessageListenerContainer getDefaultMessageListenerContainer(){
    DefaultMessageListenerContainer defmesliscont=new DefaultMessageListenerContainer();
    defmesliscont.setConnectionFactory(getMQconnectionfactory());
    defmesliscont.setSessionTransacted(true);
    defmesliscont.setDestinationName("********");
    defmesliscont.setExceptionListener(customException);
    defmesliscont.setMessageListener(messageListener);
    return defmesliscont;
}

@Bean
public SingleConnectionFactory getSingleConnectionFactory(){
    SingleConnectionFactory singleConnectionFactory=new SingleConnectionFactory();
    singleConnectionFactory.setTargetConnectionFactory(getMQconnectionfactory());
    return singleConnectionFactory;
}

@Bean
public JmsTemplate getJmsTemplate(){
    JmsTemplate jmsTemplate=new JmsTemplate();
    jmsTemplate.setConnectionFactory(getSingleConnectionFactory());
    jmsTemplate.setDefaultDestination(getMQQueue());
    return jmsTemplate;
}

public static void main(String[] args) {
    ApplicationContext ctx = SpringApplication.run(Application.class, args);

    System.out.println("Let's inspect the beans provided by Spring Boot:");

    String[] beanNames = ctx.getBeanDefinitionNames();
    Arrays.sort(beanNames);
    for (String beanName : beanNames) {
        System.out.println(beanName);
    }
}

}

但我收到此错误。

我什至尝试使用@ImportResource 导入context.xml。但这也行不通。虽然我更喜欢通过 Application.class 配置它。 请告诉我做错了什么。谢谢。

我已经成功了。这是来自三个工作 pom 文件的片段
