上篇我们介绍了搭建spring boot+Mybatis+logback+Mysql的框架搭建《spring boot项目搭建示例》
这篇博文我们介绍一下如何整合jsp页面以及将项目改成Mybatis映射文件xml的形式
步骤如下：
1.pom.xml加入jsp所需的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/xsd/maven-4.0.0.xsd">

<!-- 打包 jar -->

<plugins>
<plugin>

<configuration>

<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
<finalName>springboot</finalName>
</build>
<!-- package jar end-->
</project>2.给启动类加入如下代码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.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;
@SpringBootApplication
@ComponentScan(basePackages={"com.hu"})
@MapperScan({"com.hu.dao"})
public class MainServer extends SpringBootServletInitializer{
private final Logger log = LoggerFactory.getLogger(MainServer.class);
public static void main(String[] args) {
SpringApplication.run(MainServer.class, args);
}
//为了打包springboot-war项目
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(MainServer.class);
}
}3.application.properties配置文件加入配置
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.Driver
spring.datasource.max-idle=10
spring.datasource.max-wait=10000
spring.datasource.min-idle=5
spring.datasource.initial-size=5
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
spring.thymeleaf.cache=false
spring.thymeleaf.enabled=false
#mybatis
mybatis.mapper-locations=classpath\:mybatis/mapper/*.xml4.新建LoginController.java
package com.hu.Controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
public class LoginController {
/**
* 登录页面
* @return
*/
@RequestMapping(value = "/login",method = RequestMethod.GET)
public String login(){
System.out.println("进入到登陆页=====================");
return "login";
}
}
5.更改UserDao.java
package com.hu.dao;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;
import com.hu.entity.User;
@Mapper
public interface UserDao {
User findByName(@Param("username") String username);
int insert(@Param("username") String name, @Param("password") String password);
}
6.在resources下面新建文件夹mybatis-->在mybatis下面新建mapper文件夹-->在mapper文件夹下面建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.hu.dao.UserDao" >
<resultMap id="BaseResultMap" type="com.hu.entity.User" >
<id column="id" property="id" jdbcType="INTEGER" />
<result column="username" property="username" jdbcType="VARCHAR" />
<result column="password" property="password" jdbcType="VARCHAR" />
</resultMap>
<sql id="Base_Column_List" >
id, username, password
</sql>
<select id="findByName" resultMap="BaseResultMap" parameterType="java.lang.String" >
select
<include refid="Base_Column_List" />
from userinfo
where username = #{username,jdbcType=VARCHAR}
</select>
<insert id="insert" parameterType="com.hu.entity.User" >
insert into userinfo (username, password)
values (#{username,jdbcType=VARCHAR}, #{password,jdbcType=VARCHAR})
</insert>
</mapper>7.运行MainServer 中的main方法进行测试
①、在浏览器中输入http://localhost:8010/springboot/login
证明我们的jsp页面整合成功。
②、在浏览器中输入http://localhost:8010/springboot/find?username=xiaoming
看到这也就证明我们整合Mybatis的xml文件成功，能看到数据前提是数据库中有数据，根据自己的库进行访问。
