SpringBoot是用来简化SpringMvc开发的项目,这里自然要整合mybatis等持久化框架!
先看看项目目录:
提示:springboot热部署配置:
热部署:修改java代码后直接保存即可在浏览器上运行,不需要手动重启服务器
package com.mfc.dao;
import java.util.List;
import org.apache.ibatis.annotations.Delete;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Select;
import org.apache.ibatis.annotations.Update;
import com.mfc.entity.User;
@Mapper
public interface UserMapper {
@Select("select * from user where id = #{id}")
public User selectUserById(int id);
@Select("select * from user")
public List<User> selectAllUser();
@Insert("insert into user(userName,userAge,userAddress) values (#{userName},#{userAge},#{userAddress})")
public void addUser(User user);
@Update("update user set userName=#{userName},userAge=#{userAge},userAddress=#{userAddress} where id=#{id}")
public void updateUser(User user);
@Delete("delete from user where id=#{id}")
public void deleteUser(int id);
}

先看看项目目录:
一、在pom.xml中配置依赖jar包:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.mfc</groupId> <artifactId>springboot</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>springboot Maven Webapp</name> <url>http://maven.apache.org</url> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.4.1.RELEASE</version> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>1.1.1</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.21</version> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> </dependency> <!-- https://mvnrepository.com/artifact/javax.servlet.jsp.jstl/jstl --> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <dependency> <groupId>taglibs</groupId> <artifactId>standard</artifactId> <version>1.1.2</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <optional>true</optional> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <configuration> <fork>true</fork> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <configuration> <skip>true</skip> </configuration> </plugin> </plugins> </build> </project>
提示:springboot热部署配置:

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <optional>true</optional> </dependency>
二、项目入口:
package com.mfc; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class Application { public static void main(String[] args) { SpringApplication.run(Application.class, args); } }
三、控制器类:
package com.mfc.ctrl; import java.util.List; 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.RestController; import org.springframework.web.servlet.ModelAndView; import com.mfc.dao.UserMapper; import com.mfc.entity.User; @RestController @RequestMapping("/userController") public class UserController { @Autowired private UserMapper userMapper; @RequestMapping(value={"/selectUserById"}, method=RequestMethod.GET) public ModelAndView selectUserById(String id){ User user = userMapper.selectUserById(Integer.parseInt(id)); ModelAndView mav = new ModelAndView("updateUser"); mav.addObject("user", user); return mav; } @RequestMapping(value={"/selectAllUser"}, method=RequestMethod.GET) public ModelAndView selectAllUser(){ List<User> list = userMapper.selectAllUser(); ModelAndView mav = new ModelAndView("alluser"); mav.addObject("users", list); return mav; } @RequestMapping(value={"/addUserPage"}, method=RequestMethod.GET) public ModelAndView addUserPage(){ ModelAndView mav = new ModelAndView("adduser"); return mav; } @RequestMapping(value={"/addUser"}, method=RequestMethod.POST) public ModelAndView addUser(User user){ userMapper.addUser(user); ModelAndView mav = new ModelAndView("redirect:selectAllUser"); return mav; } @RequestMapping(value={"/updateUser"}, method=RequestMethod.POST) public ModelAndView updateUser(User user){ userMapper.updateUser(user); ModelAndView mav = new ModelAndView("redirect:selectAllUser"); return mav; } @RequestMapping(value={"/deleteUser"}, method=RequestMethod.GET) public ModelAndView deleteUser(String id){ userMapper.deleteUser(Integer.parseInt(id)); ModelAndView mav = new ModelAndView("redirect:selectAllUser"); return mav; } }
四、资源配置文件:application.properties
#配置数据库连接数据 spring.datasource.url=jdbc:mysql://localhost:3306/springboot spring.datasource.username=root spring.datasource.password=root spring.datasource.driver-class-name=com.mysql.jdbc.Driver #配置控制器里面返回页面的前后缀 spring.mvc.view.prefix=/WEB-INF/jsp/ spring.mvc.view.suffix=.jsp
五、dao层以及service层和springmvc中一样使用,实体类省略!
这里的dao层使用注解实现:package com.mfc.dao;
import java.util.List;
import org.apache.ibatis.annotations.Delete;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Select;
import org.apache.ibatis.annotations.Update;
import com.mfc.entity.User;
@Mapper
public interface UserMapper {
@Select("select * from user where id = #{id}")
public User selectUserById(int id);
@Select("select * from user")
public List<User> selectAllUser();
@Insert("insert into user(userName,userAge,userAddress) values (#{userName},#{userAge},#{userAddress})")
public void addUser(User user);
@Update("update user set userName=#{userName},userAge=#{userAge},userAddress=#{userAddress} where id=#{id}")
public void updateUser(User user);
@Delete("delete from user where id=#{id}")
public void deleteUser(int id);
}
