Dubbo笔记5——dubbo搭建web项目

1.创建提供者 03-provider-web工程

1.1创建工程

创建 Maven 的 web 工程，使用公共接口服务创建一个实现

package com.abc.provider;

import com.abc.service.SomeService;

public class SomeServiceImpl implements SomeService {
    @Override
    public String hello(String name) {
        System.out.println("执行提供者的hello()");
        return name;
    }
}

1.2 导入依赖

• dubbo2.7.0 版本依赖
• zk 客户端 curator 依赖
• servlet 与 jsp 依赖
• spring 相关依赖
• spring 需要的 commons-logging 依赖
• 自定义 00-api 依赖

1.3 web.xml

  
    
        contextConfigLocation
        classpath:spring-*.xml
    

    
    
        org.springframework.web.context.ContextLoaderListener
    

1.4 修改 spring-provider.xml

2.创建消费者 03-consumer-web

2.1 创建工程

创建 Maven 的 web 工程，导入的依赖与03-provider-web的pom相同

2.2 创建处理器

@Controller
public class SomeController {
    @Autowired
    private SomeService service;

    @RequestMapping("/some.do")
    public String someHandle() {
        String result = service.hello("China");
        System.out.println("消费者端接收到 = " +  result);
        return "/welcome.jsp";
    }
}

2.3 resources目录下配置spring-consumer.xml文件

2.4 webapp目录下定义欢迎页面index.jsp

Hello World! - consumer

2.5 webapp/WEB-INF下定义 web.xml

        CharacterEncodingFilter
        org.springframework.web.filter.CharacterEncodingFilter
        
            encoding
            utf-8
        
        
            forceEncoding
            true
        
    
    
        CharacterEncodingFilter
        /*
    

    
    
        springmvc
        org.springframework.web.servlet.DispatcherServlet
        
            contextConfigLocation
            classpath:spring-*.xml
        
        1
    
    
        springmvc
        
        *.do
