从字符串加载spring应用程序上下文

Question

Can somebody show me how to use Spring to load application context through xml string instead of file or classpath resource?

Thanks,

Answer 1

Use this:

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

i found a way doing it.

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;
}

Haven't tried it so far but can probably give a try:

// 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();
