---

在服务层工程中创建Mapper 、service ,表现层工程创建Controller,使用浏览器访问，确认是否能正常调用。

来完成一个从服务端查询实时时间的功能，测试整合是否成功

1.服务层开发

1.1编写TestMapper接口

package com.taotao.mapper;

public interface TestMapper {
	/**
	 * 从数据库中获取当前的时间
	 * @return
	 */
	public String queryNow();
}

1.2编写TestMapper.xml

	
		select NOW()
	

  

1.3编写TestService接口

package com.taotao.service;

public interface TestService {
	/**
	 * 从数据库中获取当前的时间
	 * @return
	 */
	public String queryNow();
}

 

1.4编写TestServiceImpl实现类

在写实现类的时候不能倒错service的包了，一定要导入import org.springframework.stereotype.Service这个包

不能导入import com.alibaba.dubbo.config.annotation.Service;

package com.taotao.service.impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.taotao.mapper.TestMapper;
import com.taotao.service.TestService;
@Service
public class TestServiceImpl implements TestService {
	@Autowired
	private TestMapper mapper;
	@Override
	public String queryNow() {
		return mapper.queryNow();
	}

}

 

1.5发布服务

在applicationContext-service.xml中添加

address里面填写zookeeper注册中心所处ip

  

2.表现层开发

2.1编写TestController

@Controller
public class TestController {
	@Autowired
	private TestService testservice;
	/**
	 * 测试dubbo配置是否正常
	 * @return
	 */
	@RequestMapping("/test/queryNow")
	@ResponseBody
	public String queryNow(){
		return testservice.queryNow();
	}
}

2.2引用服务

在springmvc.xml中添加：

name可以随便写，name不能冲突。

ip填写zookeeper服务器所在ip

便是要引用服务端的接口了。

 

3.测试

3.1安装taotao-manager

此时可能会报如下错误：

需要设置Java编译的环境是JDK 而不是JRE ，改成JDK即可

3.2启动taotao-manager-service

3.3启动taotao-manager-web

与启动taotao-manager-service过程一样

3.4测试访问

可能会报如下错误：

由于taotao-manager-dao层的mapper.xml没有发布过去

因为maven项目src/main/java只会发布java文件，xml文件并不会发布过去

只有src/main/resources下才会发布xml文件等。

解决方案一：

在src/main/resources下，创建对应包名如com.taotao.mapper，将mapper.xml文件放入com.taotao.mapper中

解决方案二：

在taotao-manager-dao的pom.xml中配置如下内容

将任意的properties文件、xml文件，发布到src/main/java下

		
		
		
			
				src/main/java
				
					**/*.properties
					**/*.xml
				
				false
			
		
	

 

 

 

测试成功，ssm框架整合dubbo搭建成功。
