1、创建一个maven工程命名为spring-boot-entity,pom.xml文件配置如下:
然后创建一个包,命名为com.spring.boot.entity,在该包下创建一个User.java文件,内容如下: /** * Copyright (c) Windliven 2016 All Rights Reserved * * @author liyj * @date 2017年7月11日 下午2:34:32 * @since V1.0.0 */ package com.spring.boot.entity; /** * TODO * * @author liyj * @date 2017年7月11日 下午2:34:32 * */ public class UserEntity { /** * id */ private String id; /** * name */ private String name; /** * pass */ private String pass; /** * email */ private String email; /** * iphone */ private String iphone; public UserEntity() {} public UserEntity(String id) {this.id = id;} public String getId() { return id; } public void setId(String id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getPass() { return pass; } public void setPass(String pass) { this.pass = pass; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } public String getIphone() { return iphone; } public void setIphone(String iphone) { this.iphone = iphone; } } 4.0.0 com.spring.boot.entity spring-boot-entity jar 0.0.1-SNAPSHOT releases Nexus Release Repository http://localhost:8081/nexus/content/repositories/releases/ snapshots Nexus Snapshot Repository http://localhost:8081/nexus/content/repositories/snapshots/
到此,spring-boot-entity工程创建完成。
2、创建一个maven工程,命名为spring-boot-interface,pom.xml文件配置如下:
然后创建一个包,命名为com.spring.boot.inter.service,在该包下创建UserService.java接口类。内容如下: /** * Copyright (c) Windliven 2016 All Rights Reserved * * @author liyj * @date 2017年7月11日 下午2:31:20 * @since V1.0.0 */ package com.spring.boot.inter.service; import java.util.List; import com.spring.boot.entity.UserEntity; /** * TODO * * @author liyj * @date 2017年7月11日 下午2:31:20 * */ public interface UserService { /* * insert */ void insert(UserEntity entity); /* * deleteEntity */ void deleteEntity(UserEntity entity); /* * deleteById */ void deleteById(String id); /* * updateEntity */ void updateEntity(UserEntity entity); /* * updateById */ void updateById(String id); /* * getOne */ UserEntity getOne(String id); /* * getList */ List 4.0.0 com.spring.boot.inter spring-boot-interface 0.0.1-SNAPSHOT com.spring.boot.entity spring-boot-entity 0.0.1-SNAPSHOT releases Nexus Release Repository http://localhost:8081/nexus/content/repositories/releases/ snapshots Nexus Snapshot Repository http://localhost:8081/nexus/content/repositories/snapshots/ getList(); }
到此,spring-boot-interface工程完成。
3、创建一个maven工程,命名为spring-boot-main,pom.xml文件内容如下:
4.0.0 com.spring.boot.service spring-boot-service 0.0.1-SNAPSHOT com.spring.boot.entity spring-boot-entity 0.0.1-SNAPSHOT com.spring.boot.inter spring-boot-interface 0.0.1-SNAPSHOT org.springframework.boot spring-boot 1.4.1.RELEASE org.springframework.boot spring-boot-test 1.4.1.RELEASE org.springframework.boot spring-boot-starter 1.4.1.RELEASE org.springframework.boot spring-boot-starter-web 1.4.1.RELEASE org.springframework spring-beans 4.3.1.RELEASE org.springframework spring-test 4.3.1.RELEASE org.mybatis.spring.boot mybatis-spring-boot-starter 1.1.1 org.mybatis mybatis-spring 1.2.2 org.mybatis mybatis 3.2.6 mysql mysql-connector-java 5.1.17 com.mchange c3p0 0.9.2.1 org.apache.commons commons-lang3 3.4 org.springframework.boot spring-boot-starter-cache 1.4.1.RELEASE net.sf.ehcache ehcache 2.9.0 redis.clients jedis 2.8.2 org.springframework.boot spring-boot-starter-redis 1.4.1.RELEASE org.springframework.boot spring-boot-maven-plugin 1.4.1.RELEASE releases Nexus Release Repository http://localhost:8081/nexus/content/repositories/releases/ snapshots Nexus Snapshot Repository http://localhost:8081/nexus/content/repositories/snapshots/
然后创建包,命名为com.spring.boot.base,在该包下创建DataBaseConfig.java文件,文件内容如下:
/**

*
* @author liyj
* @date 2017年7月12日 上午9:53:09

MapperScannerConfigurer msc = new MapperScannerConfigurer();
msc.setBasePackage("com.mybloc.personal.mapper");
msc.setSqlSessionFactoryBeanName("sqlSessionFactory");

}
}创建一个包,命名为com.spring.boot.dao,在该包下创建UserMapper.java文件,该文件是一个接口类,内容如下:
/**

import com.spring.boot.entity.UserEntity;
/**

*/
public interface UserMapper {
public void insertOne(UserEntity entity);
public void delete(UserEntity entity);
public void update(UserEntity entity);
public UserEntity getOne(UserEntity entity);
public List getList();
} 在src/main/resources目录下创建一个mapper文件目录,在该目录下创建UserMapper.xml文件,内容如下:
<?xml version="1.0" encoding="UTF-8" ?>insert into user(id,name,pass,email,iphone) values(#{id},#{name},#{pass},#{email},#{iphone}) delete from user where id = #{id} update user set email = #{email},iphone = #{iphone} where id = #{id}
接下来创建包,命名为:com.spring.boot.service,在该包下创建UserServiceImpl.java文件,内容如下:
/**

@Transactional(readOnly=false)
@Service
public class UserServiceImpl implements UserService {
@Autowired
private UserMapper userMapper;
/*

System.out.println("insert");
}

}
/*

@Transactional(readOnly=true)
public List getList() {
return userMapper.getList();
}
} 再创建一个包,命名为com.spring.boot.controller,在该包下创建UserController.java文件,内容如下:

//@SpringBootApplication(scanBasePackages = {"com.spring.boot"})
@RestController
@RequestMapping("/user")
public class UserController {
@Autowired
private UserService userService;
@Autowired
private CacheManager cacheManager;
@Autowired
private RedisTemplate redisTemplate;
@Value("${testName}")
private String name;
@Value("${testPass}")
private String pass;
@RequestMapping(value = "/say", method = RequestMethod.GET)
public String sayHello() {
return "hello spring boot";
}
@RequestMapping(value = "/insert", method = RequestMethod.GET)
public String insert() {
UserEntity userEntity = new UserEntity();
userEntity.setId("111");
userEntity.setName("liyj");
userEntity.setPass("123456");
userEntity.setEmail("704603154@qq.com");
userEntity.setIphone("18211140412");
userService.insert(userEntity);
return "success";
}
@RequestMapping(value = "/one/get", method = RequestMethod.GET)
public UserEntity getOne(@RequestParam String id) {
return userService.getOne(id);
}
} 接着创建一个包,命名为com.spring.boot.start,在该包下创建StartMain.java文件,内容如下:
/**
* Copyright (c) Windliven 2016 All Rights Reserved
*
* @author liyj
* @date 2017年7月11日 下午4:52:32

import org.springframework.context.annotation.Configuration;
/**
* TODO
*
* @author liyj
* @date 2017年7月11日 下午4:52:32
*
*/
@EnableAutoConfiguration
@ComponentScan(basePackages = "com.spring.boot")
@Configuration
@MapperScan(value={"com.spring.boot.dao"})
public class StartMain {
public static void main(String[] args) {
SpringApplication.run(StartMain.class, args);
}
}最后测试,启动StartMain类中的main()方法,项目便启动了,可以正常的从浏览器中访问和测试。
