一.在你創建的工程下建立 Module 選擇Spring initializr建立。html
二.在Type處選擇: Maven Project(項目的構建工具)java
三.建立依賴時勾上web,mybatis,mysql(這個看你我的須要吧,能夠自主選擇)mysql
創建好的項目結構以下:web
注意:application.properties和application.yml是同一個東西,均爲項目的核心配置文件spring
內容以下:sql
#鏈接數據庫
spring.datasource.url=jdbc:mysql://localhost:3306/smbms
spring.datasource.username=root
spring.datasource.password=1234
spring.datasource.driverClassName=com.mysql.jdbc.Driver
#引入mybatis的配置文件
mybatis:
mybatis.mapper-locations=classpath:mapper/*.xml
mybatis.type-aliases-package=com.example.sprboot.pojo
相應的pom.xml文件數據庫
<?xml version="1.0" encoding="UTF-8"?> <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.example</groupId> <artifactId>springboot</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>springboot</name> <description>Demo project for Spring Boot</description> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.5.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <!--添加web依賴--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <!--引入spring boot包--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <!-- Spring-Mybatis --> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>1.3.0</version> </dependency> <!-- MySQL --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <!--使用json對象--> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.49</version> </dependency> <!--使用thymeleaf標籤--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
相應的接口UserMapper以下:apache
@Repository public interface UserMapper { List<User> getList(); }
service以下:json
public interface UserService { List<User> getList(); }
impl以下:springboot
@Service public class UserServiceImpl implements UserService { @Resource private UserMapper userMapper; @Override public List<User> getList() { return userMapper.getList(); } }
在resources中建一個文件夾mapper裏面放mapper.xml文件,代碼以下:
<select id="getList" resultType="User"> select * from smbms_user </select>
在templates文件夾中建html文件(注意:Spring Boot中不能跳轉到.jsp文件,因此只能用html)
核心代碼以下:
<table> <th>工號</th> <th>用戶名</th> <th>姓名</th> <th>性別</th> <th>生日</th> <th>電話</th> <th>地址</th> <th>建立時間</th> <tr th:each="user : ${users}"> <td th:text="${user.id}"></td> <td th:text="${user.userCode}"></td> <td th:text="${user.userName}"></td> <td th:text="${user.gender}"></td> <td th:text="${user.birthday}"></td> <td th:text="${user.phone}"></td> <td th:text="${user.address}"></td> <td th:text="${user.createdBY}"></td> </tr> </table>
此處有一個th標籤,須要引入一個<html xmlns:th="http://www.thymeleaf.org">
並在pom.xml中引入對應的jar包(html中不能使用jstl表達式)
你們能夠擴展一下thymeleaf的知識
控制器代碼以下:
@Controller public class UserController { @Resource private UserService userService; @RequestMapping("/") public String getStuinforList(HttpServletRequest request, Model model){ List<User> list=userService.getList(); model.addAttribute("users",list); System.out.println(list); return "/index.html"; } }
