将基于Java的配置转换为基于Spring的XML

Question

我正在尝试将在java注释中完成的Birt应用程序转换为基于XML但是“我很难将此部分更改为xml

@Bean   
public BirtViewResolver birtViewResolver() throws Exception {
    BirtViewResolver bvr = new BirtViewResolver();
    bvr.setBirtEngine(this.engine().getObject());
    bvr.setViewClass(HtmlSingleFormatBirtView.class);
    bvr.setDataSource(this.birtDataServiceConfiguration.dataSource());
    bvr.setReportsDirectory("Reports");
    bvr.setOrder(2);
    return bvr;
}

我尝试了这个，但无法弄清楚如何设置birtEngine，viewClass和dataSource部分

<beans:bean id="birtViewResolver" class="org.eclipse.birt.spring.core.BirtViewResolver">
        <beans:property name="birtEngine" value="?" />
        <beans:property name="viewClass" value="?" />
        <beans:property name="dataSource" value="?" />
        <beans:property name="reportsDirectory" value="Reports" />
        <beans:property name="order" value="2" />
    </beans:bean>

提前谢谢

鉴于此

bvr.setBirtEngine(this.engine().getObject());

我将假设engine()是另一个返回@Bean对象的FactoryBean方法。在XML中，您可以将其作为

<bean name="engine" class="com.example.EngineFactoryBean" />

有关

bvr.setViewClass(HtmlSingleFormatBirtView.class);

Spring可以在XML中将完全限定的类名称作为字符串值转换为运行时的Class实例。

有关

bvr.setDataSource(this.birtDataServiceConfiguration.dataSource());

我将假设birtDataServiceConfiguration是对您@Configuration @Autowired和dataSource()为@Bean的另一个<!-- Assuming you converted that config to XML as well --> <import resource="classpath:birtDataServiceConfiguration.xml" /> <beans:bean id="birtViewResolver" class="org.eclipse.birt.spring.core.BirtViewResolver"> <beans:property name="birtEngine" ref="engine" /> <!-- You would have to give the class' fully qualified name --> <beans:property name="viewClass" value="com.example.fully.qualified.HtmlSingleFormatBirtView" /> <!-- Assuming that imported config had a bean declared with the name 'dataSource' --> <beans:property name="dataSource" ref="dataSource" /> <beans:property name="reportsDirectory" value="Reports" /> <beans:property name="order" value="2" /> </beans:bean> 课程的引用在该类中声明的方法。

生成的XML声明就像
