1. 新建Maven项目 spring-boot
2. pom.xml
<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/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.java</groupId> <artifactId>spring-boot</artifactId> <version>1.0.0</version> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.5.RELEASE</version> </parent> <dependencies> <!-- Spring Boot --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-logging</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-log4j</artifactId> <version>1.3.8.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>2.0.1</version> </dependency> <!-- 数据库连接池 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.1.11</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> </dependencies> <build> <finalName>${project.artifactId}</finalName> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.8</source> <target>1.8</target> <encoding>UTF-8</encoding> </configuration> </plugin> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <executions> <execution> <goals> <goal>repackage</goal> </goals> </execution> </executions> </plugin> </plugins> </build> </project>
3. 启动类 Starter.java
package com.java.springboot; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.builder.SpringApplicationBuilder; import org.springframework.boot.web.servlet.support.SpringBootServletInitializer; /** * 启动类 * * @author Logan * @version 1.0.0 * */ @SpringBootApplication public class Starter extends SpringBootServletInitializer { public static void main(String[] args) { SpringApplication.run(Starter.class, args); } @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) { return builder.sources(Starter.class); } }
4. User.java
package com.java.springboot.pojo; public class User { private String id; private String username; private String password; private Integer age; public String getId() { return id; } public void setId(String 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; } public Integer getAge() { return age; } public void setAge(Integer age) { this.age = age; } @Override public String toString() { return "User [id=" + id + ", username=" + username + ", password=" + password + ", age=" + age + "]"; } }
5. UserMapper.java
package com.java.springboot.mapper; import java.util.List; import com.java.springboot.pojo.User; public interface UserMapper { Integer checkLogin(User user); List<User> findUserList(User user); void addUser(User user); void updateUser(User user); void deleteUser(User user); }
6. UserMapper.xml
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.java.springboot.mapper.UserMapper"> <!-- 配置数据库字段和实体类映射 --> <resultMap id="userMap" type="com.java.springboot.pojo.User"> <id property="id" column="id" /> <result property="username" column="username" /> <result property="password" column="password" /> <result property="age" column="age" /> </resultMap> <!-- 检查登录 --> <select id="checkLogin" parameterType="com.java.springboot.pojo.User" resultType="java.lang.Integer"> select 1 from user where username=#{username} and password=#{password} </select> <!-- 查询用户列表 --> <select id="findUserList" parameterType="com.java.springboot.pojo.User" resultType="com.java.springboot.pojo.User"> select id,username,password,age from user </select> <!-- 新增用户 --> <insert id="addUser" parameterType="com.java.springboot.pojo.User" > <selectKey keyProperty="id" order="BEFORE" resultType="java.lang.String"> select replace(uuid(), \'-\', \'\') as id from dual </selectKey> insert into user(id,username,password,age) values(#{id},#{username},#{password},#{age}); </insert> <!-- 修改用户信息 --> <update id="updateUser" parameterType="com.java.springboot.pojo.User" > update user set username=#{username}, password=#{password}, age=#{age} where id=#{id} </update> <!-- 根据id删除用户 --> <delete id="deleteUser" parameterType="java.lang.String"> delete from user where id=#{id} </delete> </mapper>
7、UserService.java
package com.java.springboot.service; import java.util.List; import com.java.springboot.pojo.User; public interface UserService { Integer checkLogin(User user); List<User> findUserList(User user); void addOrUpdateUser(User user); void deleteUser(User user); }
8、UserServiceImpl.java
package com.java.springboot.service.impl; import java.util.List; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import org.springframework.transaction.annotation.Transactional; import com.java.springboot.mapper.UserMapper; import com.java.springboot.pojo.User; import com.java.springboot.service.UserService; @Service("userService") public class UserServiceImpl implements UserService { @Autowired private UserMapper userMapper; @Override public Integer checkLogin(User user) { return userMapper.checkLogin(user); } @Override public List<User> findUserList(User user) { return userMapper.findUserList(user); } @Override @Transactional public void addOrUpdateUser(User user) { if (null == user.getId() || user.getId().isEmpty()) { userMapper.addUser(user); } else { userMapper.updateUser(user); } } @Override @Transactional public void deleteUser(User user) { userMapper.deleteUser(user); } }
9、UserController.java
package com.java.springboot.controller; import java.util.List; import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; import com.java.springboot.pojo.User; import com.java.springboot.service.UserService; @Controller @RequestMapping("/user") public class UserController { private static final Log LOG = LogFactory.getLog(UserController.class); @Autowired private UserService userService; @RequestMapping("/login") public String login() { return "user/login"; } @RequestMapping("/checkLogin") public String checkLogin(User user, Model model) { LOG.info("Into checkLogin"); System.out.println(user); String responseUrl = null; // 检查用户名密码是否存在 Integer result = userService.checkLogin(user); System.out.println("result: " + result); LOG.info("result: " + result); // 绑定用户名密码输出返回 if (null == result) { model.addAttribute("username", user.getUsername()); model.addAttribute("password", user.getPassword()); responseUrl = "user/login"; } // 登录成功，访问主页 else { responseUrl = "user/main"; } LOG.info("Exit checkLogin"); return responseUrl; } @ResponseBody @RequestMapping("/findUserList") public List<User> findUserList(User user) { LOG.info("Into findUserList"); System.out.println(user); List<User> list = userService.findUserList(user); LOG.info("Exit findUserList"); return list; } @RequestMapping("/toAddOrUpdateUser") public String toAddOrUpdateUser(User user, Model model) { LOG.info("Into toAddOrUpdateUser"); System.out.println("user: " + user); // 输出id，根据id是否为空，判断是新增还是修改 model.addAttribute("user", user); LOG.info("Exit toAddOrUpdateUser"); return "user/addOrUpdateUser"; } @RequestMapping("/addOrUpdate") public String addOrUpdate(User user) { LOG.info("Into addOrUpdate"); System.out.println("user: " + user); userService.addOrUpdateUser(user); System.out.println(user); LOG.info("Exit addOrUpdate"); return "user/main"; } @ResponseBody @RequestMapping("/deleteUser") public String deleteUser(User user) { System.out.println(user); LOG.info("Into deleteUser"); userService.deleteUser(user); LOG.info("Exit deleteUser"); return "删除成功！"; } }
10、ApplicationConfig.java
package com.java.springboot.config; import org.mybatis.spring.annotation.MapperScan; import org.springframework.context.annotation.Configuration; /** * 配置类 * * @author Logan * @version 1.0.0 * */ @Configuration @MapperScan({ "com.java.springboot.mapper" }) public class ApplicationConfig { }

13、log4j.properties
log4j.rootLogger= INFO, stdout,logfile
log4j.logger.INFO=INFO,logfile
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH\\:mm\\:ss.SSS} [%5p] [%c] - %m%n
log4j.appender.logfile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.logfile.File=G:/Java/logs/springboot/LogFile.log
log4j.appender.logfile.DatePattern=\'_\'yyyy-MM-dd\'.log\'
log4j.appender.logfile.Threshold=INFO
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=%d{yyyy-MM-dd HH\\:mm\\:ss} [%5p] - %m%n
log4j.appender.logfile.Append=true
14、/static/index.html
<!DOCTYPE html> <html> <head> <title>登录</title> <meta http-equiv="content-type" content="text/html; charset=UTF-8" /> <script type="text/javascript"> function addUser() { location.href = "/user/toAddOrUpdateUser"; } </script> </head> <body> <form action="/user/checkLogin" method="post"> <table> <tr> <td>用户名：</td> <td><input name="username" /><br /></td> </tr> <tr> <td>密码：</td> <td><input type="password" name="password" /><br /></td> </tr> <tr> <td><input type="submit" value="登录" /></td> <td><input type="button" value="注册" onclick="addUser();" /></td> </tr> </table> </form> </body> </html>
15、/views/user/login.html
<!DOCTYPE html> <html xmlns:th="http://www.thymeleaf.org"> <head> <title>登录</title> <meta http-equiv="content-type" content="text/html; charset=UTF-8" /> <script type="text/javascript"> function addUser() { location.href = "/user/toAddOrUpdateUser"; } </script> </head> <body> <form action="/user/checkLogin" method="post"> <table> <tr> <td>用户名：</td> <td><input name="username" th:value="${username}" /><br /></td> </tr> <tr> <td>密码：</td> <td><input type="password" name="password" th:value="${password}" /><br /></td> </tr> <tr> <td><input type="submit" value="登录" /></td> <td><input type="button" value="注册" onclick="addUser();" /></td> </以上是关于springboot框架快速搭建的主要内容，如果未能解决你的问题，请参考以下文章springboot入门--快速搭建一个springboot框架
