将基于XML的Spring转换为基于Java的配置 [英] Convert Spring XML-based to Java-Based Configuration

问题描述

我尽量不要使用任何xml。

I try not to using any xml.

<bean id="restTemplate" class="org.springframework.web.client.RestTemplate">

    <property name="messageConverters">
        <list>
            <bean class="org.springframework.http.converter.xml.MarshallingHttpMessageConverter">
                <property name="marshaller" ref="jaxbMarshaller"/>
                <property name="unmarshaller" ref="jaxbMarshaller"/>
            </bean>
            <bean class="org.springframework.http.converter.FormHttpMessageConverter"/>
        </list>
    </property>
</bean>

像这样：convert to @Bean

like this one: convert to @Bean

@Bean
public RestTemplate restTemplate() {
    RestTemplate restTemplate = new RestTemplate();
    List<HttpMessageConverter<?>> converters = new ArrayList<HttpMessageConverter<?>>();

    converters.add(marshallingMessageConverter());
    restTemplate.setMessageConverters(converters);

    return restTemplate;
}

这里有问题。

<bean id="jaxbMarshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
    <property name="classesToBeBound">
        <list>
            <value>com.cloudlb.domain.User</value>
        </list>
    </property>
</bean>

尝试将com.cloudlb.domain.User转换为Class [] not thing work。 / p>

Try to convert "com.cloudlb.domain.User" into Class [] not thing work.

@Bean
public MarshallingHttpMessageConverter marshallingMessageConverter() {
    Jaxb2Marshaller marshaller = new Jaxb2Marshaller();

    //
    List<Class<?>> listClass = new ArrayList<Class<?>>();
    listClass.add(User.class);

    marshaller.setClassesToBeBound((Class<?>[])listClass.toArray());
    // --------------------------------

    return new MarshallingHttpMessageConverter(marshaller, marshaller);
}

错误：铸造有问题。

提前谢谢。

推荐答案

@Bean
public MarshallingHttpMessageConverter marshallingMessageConverter() {
    return new MarshallingHttpMessageConverter(
        jaxb2Marshaller(),
        jaxb2Marshaller()
    );
}

@Bean
public Jaxb2Marshaller jaxb2Marshaller() {
    Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
    marshaller.setClassesToBeBound(new Class[]{
               twitter.model.Statuses.class
    });
    return marshaller;
}
