Apache CXF结合camel blueprint demo

cxf框架是apache的web service框架，提供简单易用的webservice功能，同时可以实现restful风格的soa。

camel也是apache出品，他将request到response以route的形式进行处理，同时将response返回给请求端。这一点类似前端emberjs的思路，每一个请求都通过一个route作为入口，然后根据XML的配置经过每个处理，最后将结果返回。

为了方便实用和配置，camel同时提供了blueprint的配置方式，将请求配置到xml文件中，从而可以更加清晰的了解访问路由，利于维护。

 

本例是基于jboss fuse， karaf的osgi程序。

1. java程序代码：

2. @Path("/")
   @Consumes(MediaType.APPLICATION_JSON)
   public interface LoginEndPoint{
   
   @POST
   @Produces(MediaType.APPLICATION_JSON)
   @Path("/addCustomer")
   public String addCustomer(CustomerVo cust);
   
   @POST
   @Produces(MediaType.APPLICATION_JSON)
   @Path("/loginCustomer/{name}")
   public CustomerVo loginCustomer(@PathParam("name")String name);
   }

    具体business实现

   public class LoginEndPointImpl implements LoginEndPoint{
   
   @Override
   public String addCustomer(CustomerVo cust){
   
   return null;
   }
   
   @Override
   public CustomerVo loginCustomer(String name){
   
   return null;
   }
   }

    

   public interface Processor{
   
   public Object process(String name);
   }

    
   Processor 实现

   public LoginCustomerProcessor implements Processor{
   
   public Object process(String name){
   
   CustomerVo cust=new CustomerVo();
   cust.setName(name);
   cust.setStatus("Y");
   return cust;
   }
   }

    
3. blueprint.xml默认配置路径在./resources/OSGI-INF/blueprint/blueprint.xml

<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
