使用ssm框架构建java web总结（搭建简易的网页）
使用ssm框架构建java web总结（搭建简易的网页）<dependency> <!--添加jsp依赖 -->依次点击，创建项目二．添加pom.xml依赖因为springboot不推荐使用jsp做页面，如果想要使用就必需的添加jsp的依赖
还是我的风格，话不多说，直接上干货。
开发工具：idea
开发环境：java8
一．创建项目
依次点击，创建项目
二．添加pom.xml依赖
因为springboot不推荐使用jsp做页面，如果想要使用就必需的添加jsp的依赖
<!--添加jsp依赖 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</dependency>
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
</dependency>
三．spring boot整合spring mvc
因为在创建项目的时候我们选择了mybatis和jdbc所以在这里也要把他们两也给配置进去
1.编辑application.properties
# 页面默认前缀目录
spring.mvc.view.prefix=/WEB-INF/jsp/
# 响应页面默认后缀
spring.mvc.view.suffix=.jsp
#开发配置
spring.datasource.driverClassName = com.Mysql.jdbc.Driver
spring.datasource.url = jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8
spring.datasource.username = root
spring.datasource.password = 123456
# mybatis接口文件位置
mybatis.mapper-locations: classpath:mapper/*.xml
mybatis.type-aliases-package: com.chaoqi.springboot_demo2.domain
2编辑完application.properties之后再src/mian下创建webapp目录，结构如下
目录结构
index.jsp文件内容如下 <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> this is springboot </body> </html>
3新建IndexController
package com.chaoqi.springboot_test.web;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class IndexController {
private static final String INDEX = "index";
@RequestMapping("/show")
public String getIndex() {
return INDEX;
}
}
4创建完成后整体结构如下图
整体结构图
5运行main函数
6访问页面 localhost：8080//show，成功
四、springboot整合mybatis
1.创建数据表
Cmd命令行窗口。Mysql：Test数据库下创建新表并加入数据
建表
CREATE TABLE `music_info` (
`id` int(10) NOT NULL AUTO_INCREMENT COMMENT '主键id'
`singer_name` varchar(100) NOT NULL COMMENT '歌手名'
`music_size` varchar(100) NOT NULL COMMENT '歌曲大小'
`music_name` varchar(100) NOT NULL COMMENT '歌曲名'
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8;
插入三条数据
INSERT INTO `music_info` VALUES ('1' '小三' '3.2M' '起风了');
INSERT INTO `music_info` VALUES ('2' '刘德华' '3.0M' '忘情水');
INSERT INTO `music_info` VALUES ('3' '猪点点' '5.0M' '会写程序的小猪');
2.创建pojo
package com.chaoqi.springboot_test.dao.domain;
public class MusicInfo {
// 主键id
private Integer id;
// 歌手名
private String singerName;
// 歌曲大小
private String musicSize;
// 歌曲名
private String musicName;
/**
* 获取 主键id music_info.id
*
* @return 主键id
*/
public Integer getId() {
return id;
}
/**
* 设置 主键id music_info.id
*
* @param id 主键id
*/
public void setId(Integer id) {
this.id = id;
}
/**
* 获取 歌手名 music_info.singer_name
*
* @return 歌手名
*/
public String getSingerName() {
return singerName;
}
/**
* 设置 歌手名 music_info.singer_name
*
* @param singerName 歌手名
*/
public void setSingerName(String singerName) {
this.singerName = singerName == null ? null : singerName.trim();
}
/**
* 获取 歌曲大小 music_info.music_size
*
* @return 歌曲大小
*/
public String getMusicSize() {
return musicSize;
}
/**
* 设置 歌曲大小 music_info.music_size
*
* @param musicSize 歌曲大小
*/
public void setMusicSize(String musicSize) {
this.musicSize = musicSize == null ? null : musicSize.trim();
}
/**
* 获取 歌曲名 music_info.music_name
*
* @return 歌曲名
*/
public String getMusicName() {
return musicName;
}
/**
* 设置 歌曲名 music_info.music_name
*
* @param musicName 歌曲名
*/
public void setMusicName(String musicName) {
this.musicName = musicName == null ? null : musicName.trim();
}
@Override
public String toString() {
return "MusicInfo{"
"id=" id
" singerName='" singerName '\''
" musicSize='" musicSize '\''
" musicName='" musicName '\''
'}';
}
}
3.创建mapper.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.chaoqi.springboot_test.dao.mapper.MusicInfoMapper">
<resultMap id="BaseResultMap" type="com.chaoqi.springboot_test.dao.domain.MusicInfo">
<id column="id" jdbcType="INTEGER" property="id" />
<result column="singer_name" jdbcType="VARCHAR" property="singerName" />
<result column="music_size" jdbcType="VARCHAR" property="musicSize" />
<result column="music_name" jdbcType="VARCHAR" property="musicName" />
</resultMap>
</mapper>
4创建mapper
package com.chaoqi.springboot_test.dao.mapper;
import com.chaoqi.springboot_test.dao.domain.MusicInfo;
import org.apache.ibatis.annotations.ResultMap;
import org.apache.ibatis.annotations.Select;
import java.util.List;
public interface MusicInfoMapper {
@ResultMap("BaseResultMap")
@Select("select * from music_info")
List<MusicInfo> selectAll(MusicInfo musicInfo);
}
5.service接口
package com.chaoqi.springboot_test.service;
import com.chaoqi.springboot_test.dao.domain.MusicInfo;
import java.util.List;
public interface MusicInfoService {
public List<MusicInfo> getMusicInfo(MusicInfo musicInfo);
}
6.servise实现类
package com.chaoqi.springboot_test.service.impl;
import com.chaoqi.springboot_test.dao.domain.MusicInfo;
import com.chaoqi.springboot_test.dao.mapper.MusicInfoMapper;
import com.chaoqi.springboot_test.service.MusicInfoService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
@Service
public class MusicInfoServiceImpl implements MusicInfoService {
@Autowired
private MusicInfoMapper musicInfoMapper;
@Override
public List<MusicInfo> getMusicInfo(MusicInfo musicInfo) {
List<MusicInfo> musicInfos = musicInfoMapper.selectAll(null);
return musicInfos;
}
}
7.编辑indexcontroller
package com.chaoqi.springboot_test.web;
import com.chaoqi.springboot_test.dao.domain.MusicInfo;
import com.chaoqi.springboot_test.service.MusicInfoService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import java.util.List;
@Controller
public class IndexController {
private static final String INDEX = "index";
@Autowired
private MusicInfoService musicInfoService;
@RequestMapping("/show")
public String getIndex() {
return INDEX;
}
@RequestMapping("/music")
@ResponseBody
public List<MusicInfo> getMusicInfo(MusicInfo musicInfo) {
List<MusicInfo> musicInfoList = musicInfoService.getMusicInfo(null);
return musicInfoList;
}
}
8.给SpringbootTestApplication类加上注解@MapperScan("com.chaoqi.springboot_test.dao.mapper")
package com.chaoqi.springboot_test;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@SpringBootApplication
@MapperScan("com.chaoqi.springboot_test.dao.mapper")
public class SpringbootTestApplication {
public static void main(String[] args) {
SpringApplication.run(SpringbootTestApplication.class args);
}
}
9.运行项目，成功，springboot springmvc mybatis整合完成
Localhost:8080/music
