Java RPC增加spring定义支持

<bean id="demoService" class="lu.tool.provider.DemoServiceImpl" />
<rpc:service interface="lu.tool.provider.DemoService" ref="demoService" />
 ^                 ^                                   ^
 |- xsd:element    |- xsd:attribute                    |- xsd:attribute

XML Schema Definition

NamespaceHandler

    @Override
    public void init() {
        registerBeanDefinitionParser("service", new RpcBeanDefinitionParser(ServiceConfigBean.class));
    }

BeanDefinitionParser
