springboot+mybatis+zookeeper+dubbo的组合使用
这个Demo的基本结构就是provider+consumer+interface
1.首先创建一个maven工程interface,接口工程的具体结构如下:
2.接着创建提供者provider
2.1 pom文件编写如下代码
com.kinglong.springboot
springboot-dubbo-provider
1.0.0
4.0.0
org.springframework.boot
spring-boot-starter-parent
1.5.9.RELEASE
UTF-8
UTF-8
1.8
org.springframework.boot
spring-boot-starter-web
org.springframework.boot
spring-boot-starter-test
test
com.alibaba.spring.boot
dubbo-spring-boot-starter
1.0.0
com.101tec
zkclient
0.10
com.kinglong.springboot
springboot-dubbo-interface
1.0.0
org.mybatis.spring.boot
mybatis-spring-boot-starter
1.3.1
mysql
mysql-connector-java
org.mybatis.generator
mybatis-generator-maven-plugin
1.3.6
src/main/resources/GeneratorMapper.xml
true
true
2.3 继续创建resources文件下的主配置文件,因为要采用maven生成映射文件mapper.所以同时创建一个GeneratorMapper.xml的配置文件,其生成映射文件的依赖包已经在pom文件
application.properties内容如下:
# WEB服务端口
server.port=9200
# dubbo配置
spring.dubbo.appname=14-springboot-all-dubbo-provider
spring.dubbo.registry=zookeeper://192.168.174.129:2181
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://192.168.174.129:3306/springdb?useUnicode=true&characterEncoding=utf8&useSSL=false
点击生成之后如下提示:
因为model类在interface中已经创建,所以在这里创建的要删除他.在这里用不到.
因为使用的是注解开发,所以在映射文件中要添加注解@Mapper如果在此处不添加注解,就需要在main方法类Application中添加了,使用起来会繁琐一点.
2.4创建业务实现类UserServiceImpl
具体如下:
package com.kinglong.springboot.service.impl;
import com.kinglong.springboot.model.User;
import com.kinglong.springboot.service.UserService;
import org.springframework.stereotype.Service;
import java.util.List;
import java.util.Map;
//spring的service注解
@Service
//dubbo的service注解
@com.alibaba.dubbo.config.annotation.Service
public class UserServiceImpl implements UserService{
@Override
public User getUser(Integer id) {
return null;
}
@Override
public int addUser(User user) {
return 0;
}
@Override
public int updateUser(User user) {
return 0;
}
@Override
public int deleteUser(Integer id) {
return 0;
}
@Override
public List getUserByPage(Map paramMap) {
return null;
}
@Override
public int getUserByTotal() {
return 0;
}
} 
3.创建消费者consumer
3.1检查pom文件依赖,添加所需依赖,具体如下:
com.kinglong.springboot
springboot-dubbo-consumer
1.0.0
4.0.0
org.springframework.boot
spring-boot-starter-parent
1.5.9.RELEASE
UTF-8
UTF-8
1.8
org.springframework.boot
spring-boot-starter-web
org.springframework.boot
spring-boot-starter-test
test
com.alibaba.spring.boot
dubbo-spring-boot-starter
1.0.0
com.101tec
zkclient
0.10
com.kinglong.springboot
springboot-dubbo-interface
1.0.0
org.springframework.boot
spring-boot-starter-thymeleaf
net.sourceforge.nekohtml
nekohtml
org.unbescape
unbescape
1.1.5.RELEASE
org.springframework.boot
spring-boot-maven-plugin
又一个重点来了!由于springboot推荐使用的前端展示页面为thymeleaf,所以这里添加了thymeleaf的依赖包
3.2 依旧接着创建springboot的main方法类,因为是集成dubbo框架,所以记得添加注解@EnableDubboConfiguration
3.3继续创建resources文件中的主配置文件以及前端展示页面user.html
application.properties内容如下:
# WEB服务端口
server.port=9100
# dubbo配置
spring.dubbo.appname=14-springboot-all-dubbo-provider
spring.dubbo.registry=zookeeper://192.168.174.129:2181
#开发阶段，建议关闭thymeleaf的缓存
spring.thymeleaf.cache=false
#使用遗留的html5以去掉对html标签的校验
spring.thymeleaf.mode=LEGACYHTML5
spring.mvc.view.prefix=/
spring.mvc.view.suffix=.html
Spring boot集成 Thymeleaf
package com.kinglong.springboot.controller;
import com.alibaba.dubbo.config.annotation.Reference;
import com.kinglong.springboot.model.User;
import com.kinglong.springboot.service.UserService;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import java.util.List;
import java.util.Map;
import java.util.concurrent.ConcurrentHashMap;
@Controller
public class UserController {
@Reference
private UserService userService;
@RequestMapping("/all/index")
public String index (Model model,
@RequestParam(value="currentPage", required = false) Integer currentPage) {
int pageSize = 10;
if (null == currentPage) {
currentPage = 1;
}
int totalRow = userService.getUserByTotal();
int totalPage = totalRow / pageSize;
int left = totalRow % pageSize;
if (left > 0) {
totalPage = totalPage + 1;
}
int startRow = (currentPage-1) * pageSize;
Map paramMap = new ConcurrentHashMap<>();
paramMap.put("startRow", startRow);
paramMap.put("pageSize", pageSize);
List userList = userService.getUserByPage(paramMap);
model.addAttribute("userList", userList);
return "user";
}
} 
总结:这是最基本的springboot集成各框架运行的Demo,熟练应运他之后相信springboot框架也会很熟练的,其实,springboot框架只是在spring框架的基础上再次做了集成,所以,如果spring框架如果用的熟练的话,相信一定会很快地掌握的.
