springboot项目

中国加油，武汉加油！

篇幅较长，配合目录观看

案例准备

  1. 本案例基于linux篇】八. zookeeper和dubbo安装配置
  2. git地址 https://gitee.com/springboot-dubbo/nz1904-springboot-dubbo

1. 创建nz1904-springboot-dubb（maven）

1.1 删除src作为站点工程

1.2 pom继承springboot

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

        <groupId>org.example</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.wpj</groupId>
    <artifactId>user-entity</artifactId>

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

import java.io.Serializable;

@Data
@NoArgsConstructor
@AllArgsConstructor
@TableName("user")
public class User implements Serializable {
    @TableId(type = IdType.AUTO)
    private Integer id;
    private String name;
    private String pwd;
    private Integer sex;
}

2.3 编写sql脚本

DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) DEFAULT NULL,
  `pwd` varchar(255) DEFAULT NULL,
  `sex` int(11) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=latin1;

INSERT INTO `user` VALUES ('1', 'wpj', '123', '1');
INSERT INTO `user` VALUES ('2', 'jiekami', '123', '1');

@SpringBootTest
@RunWith(SpringRunner.class)
public class TestService {

    @Autowired
    private IUserService iUserService;

    @Test
    public void testService(){
        System.out.println(iUserService.getList());
    }

}

6. 使用dubbo发布服务

6.1 user-service-impl导dubbo依赖

<!-- dubbo依赖 -->
<dependency>
   <groupId>com.alibaba.boot</groupId>
   <artifactId>dubbo-spring-boot-starter</artifactId>
   <version>0.2.0</version>
</dependency>

6.2 修改Impl的注解

import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@DubboComponentScan(basePackages = "com.wpj")
@MapperScan(basePackages = "com.wpj.mapper")
public class UserServiceImplApplication {
    public static void main(String[] args) {
        SpringApplication.run(UserServiceImplApplication.class, args);
    }
}

6.4 配置dubbo

# 配置dubbo
