Question

有人可以告诉我如何使用Spring通过xml字符串而不是文件或类路径资源来加载应用程序上下文吗？

谢谢，

Answer 1

使用此：

String contextXML = ...;
Resource resource = new ByteArrayResource(contextXML.getBytes());
GenericXmlApplicationContext springContext = new GenericXmlApplicationContext();
springContext.load(resource);
Object myBean = springContext.getBean("myBean");
...

礼

Answer 2

我找到了一种方法。

public MyApplicationContext(String xml,
        ApplicationContext parent){

    super(parent);

    this.configResources = new Resource[1];

    configResources[0] = new ByteArrayResource(xml.getBytes());


    refresh();
}


private Resource[] configResources;

protected Resource[] getConfigResources() {
    return this.configResources;
}

到目前为止还没试过，但可以尝试一下：

// define and open the input stream from which we read the configuration
InputStream input = new ByteArrayInputStream("string".getBytes("UTF-8"));
// create the bean factory
DefaultListableBeanFactory beans = new DefaultListableBeanFactory();
XmlBeanDefinitionReader reader = new XmlBeanDefinitionReader(beans);
reader.setValidationMode(XmlBeanDefinitionReader.VALIDATION_XSD);
reader.loadBeanDefinitions(new InputStreamResource(input));
beans.preInstantiateSingletons();
input.close();

@Ref：http://beradrian.wordpress.com/2010/03/30/load-spring-from-input-stream/ 让我知道它是否有效......
