spring boot项目搭建示例①
所用技术：JDK1.7、Mysql、spring boot、Logback、Mybatis
开发工具：Myeclipse、Maven
1.数据库创建：
CREATE TABLE `userinfo` (
`id` int(20) NOT NULL AUTO_INCREMENT,
`username` varchar(20) DEFAULT NULL,
`password` varchar(20) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf82.创建Maven工程
步骤：
①、Ctrl+N-->选择Maven Project
②、勾选Create a simple project (skip archetype selection)-->点击Next
③、输入Group Id、Artifact Id，选择packaging为war,点击Finish
项目结构如下：
3、导入spring boot所需jar包
pom.xml：
4.0.0
com.hu
SpringBootPro
0.0.1-SNAPSHOT
war
org.springframework.boot
spring-boot-starter-parent
1.5.9.RELEASE
pom
org.springframework.boot
spring-boot-starter-web
1.5.9.RELEASE
org.springframework.boot
spring-boot-starter-test
1.5.9.RELEASE
test
4.增加application.properties属性文件
在src/main/resources下新建文件
application.properties:
server.port=8010
server.contextPath=/springboot5、增加启动类
MainServer.java:
package com.hu.server;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class MainServer {
public static void main(String[] args) {
SpringApplication.run(MainServer.class, args);
}
}项目结构如下：
6、启动测试
现在可以检查一下是否搭建成功了，在MainServer中右键-->run as/debug as -->java application
控制台出现如下便是成功了：
7.编写第一个测试接口
①、将MainServer.java申明当前为Controller
②、添加测试接口地址
③、启动main方法，前端访问
代码如下：
package com.hu.server;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
@SpringBootApplication
public class MainServer {
public static void main(String[] args) {
SpringApplication.run(MainServer.class, args);
}
@RequestMapping(value = "/hello")
public @ResponseBody String hello(){
return "Hello Boot";
}
}前端访问接口：
8、整合日志框架
①、导入日志jar包pom.xml下增加：
org.springframework.boot
spring-boot-starter-logging
1.5.9.RELEASE
②、增加logback.xml配置文件，放到resource目录下
%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n
${LOG_HOME}/TestSpringBoot_info.log.%d{yyyy-MM-dd}.log
30
info
ACCEPT
DENY
%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n
10MB
${LOG_HOME}/TestSpringBoot_error.log.%d{yyyy-MM-dd}.log
30
error
ACCEPT
DENY
%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n
10MB
代码引用：
9、整合Mybatis
①、导入Mybatis和Mysql的jar包
org.mybatis.spring.boot
mybatis-spring-boot-starter
1.3.1
mysql
mysql-connector-java
5.1.30
②、在application.properties文件中配置数据库连接信息
server.port=8010
server.contextPath=/springboot
spring.datasource.url=jdbc:mysql://localhost:3306/test
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver③、新建Controller、entity、service、dao包
④、添加接口、实现类、实体、sql语句
User.java:
package com.hu.entity;
public class User{
private int id;
private String username;
private String password;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
@Override
public String toString() {
return "Customer [id=" + id + ", username=" + username + ", password="
+ password + "]";
}
}
UserDao.java:
package com.hu.dao;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Select;
import com.hu.entity.User;
@Mapper
public interface UserDao {
@Select("select * from userinfo where username = #{username}")
User findByName(@Param("username") String username);
@Insert("insert into userinfo (username, password) values(#{username}, #{password})")
int insert(@Param("username") String name, @Param("password") String password);
}
UserService.java:
package com.hu.service;
import org.springframework.stereotype.Service;
import com.hu.entity.User;
@Service("userService")
public interface UserService {
//查询
public User findByname(String username);
//增加
public int insertUser(String username,String password);
}
UserServiceImpl.java:
package com.hu.service.impl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.hu.dao.UserDao;
import com.hu.entity.User;
import com.hu.service.UserService;
@Service("userService")
public class UserServiceImpl implements UserService {
@Autowired
UserDao userDao;
@Override
public User findByname(String username) {
// TODO Auto-generated method stub
User userinfo = userDao.findByName(username);
return userinfo;
}
@Override
public int insertUser(String username, String password) {
// TODO Auto-generated method stub
return userDao.insert(username, password);
}
}
UserController.java:
package com.hu.Controller;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import com.hu.entity.User;
import com.hu.service.UserService;
@Controller
public class UserController {
private final Logger log = LoggerFactory.getLogger(UserController.class);
@Autowired
private UserService userService;
@RequestMapping(value = "/add",method = RequestMethod.GET)
public @ResponseBody String addUser() {
userService.insertUser("xiaoming","111111");
return "插入成功";
}
@RequestMapping(value="/find",method=RequestMethod.GET)
public @ResponseBody User queryUserByName(String username){
User userinfo = userService.findByname(username);
return userinfo;
}
}MainServer.java:
package com.hu.server;
import org.mybatis.spring.annotation.MapperScan;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
@SpringBootApplication
@ComponentScan(basePackages={"com.hu"})
@MapperScan({"com.hu.dao"})
public class MainServer {
private final Logger log = LoggerFactory.getLogger(MainServer.class);
public static void main(String[] args) {
SpringApplication.run(MainServer.class, args);
}
}10.测试接口数据插入及查询
①、启动主函数
②、测试接口
