------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥-------------
本此博客记录一套考试题，随后我把项目以及题目发到github上，简单的说一下springboot的开发
本此考试题用Spring+SpringMVC+MyBatis+SpringBoot+MySQL+Druid+.yml配置文件+thymeleaf模板引擎
我会把大量源码放上来，以及整合需要的注意点，大家可以一会去github上下载观看
项目概览：
一，jar包，pom.xml中的配置
4.0.0 z05springbootmyself_exam war z05springbootmyself_exam Maven Webapp http://www.example.com org.springframework.boot spring-boot-starter-parent 2.0.3.RELEASE UTF-8 UTF-8 1.8 org.springframework.boot spring-boot-starter org.springframework.boot spring-boot-starter-logging org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-devtools true runtime mysql mysql-connector-java runtime org.springframework.boot spring-boot-starter-test test org.mybatis.spring.boot mybatis-spring-boot-starter 1.3.1 com.alibaba fastjson 1.2.12 com.alibaba druid 1.0.18 org.mybatis mybatis 3.4.1 org.springframework.boot spring-boot-starter-thymeleaf org.springframework.boot spring-boot-starter-jdbc com.github.pagehelper pagehelper-spring-boot-starter 1.2.3 z05springbootmyself_exam org.springframework.boot spring-boot-maven-plugin src/main/java **/*.properties **/*.xml
注意点：如果自己工程不是通过官网骨架创建，自己粘的话，小心粘了俩个parent节点，他不会报错，但是在后续就不会下载jar包了
二，数据库脚本，我给一份
DROP TABLE IF EXISTS `air_quality_index`;CREATE TABLE `air_quality_index` ( `id` int(11) NOT NULL AUTO_INCREMENT, `district` varchar(255) NOT NULL, `monitorTime` datetime NOT NULL ON UPDATE CURRENT_TIMESTAMP, `pm10` int(255) NOT NULL, `pm25` int(255) NOT NULL, `monitoringStation` varchar(255) NOT NULL, `createDate` datetime NOT NULL ON UPDATE CURRENT_TIMESTAMP, PRIMARY KEY (`id`)) ENGINE=InnoDB AUTO_INCREMENT=12 DEFAULT CHARSET=utf8;-- ------------------------------ Records of air_quality_index-- ----------------------------INSERT INTO `air_quality_index` VALUES ('1', '西城区', '2018-05-22 09:34:05', '243', '176', '灵境胡同监测站', '2018-05-22 10:57:21');INSERT INTO `air_quality_index` VALUES ('2', '东城区', '2018-05-22 09:34:05', '27', '33', '东四监测站', '2018-05-22 09:34:35');INSERT INTO `air_quality_index` VALUES ('3', '海淀区', '2018-05-22 09:34:05', '21', '30', '航天桥监测站', '2018-05-22 09:34:35');INSERT INTO `air_quality_index` VALUES ('4', '丰台区', '2018-05-22 09:34:05', '24333', '17', '七里庄监测站', '2018-05-22 10:55:20');INSERT INTO `air_quality_index` VALUES ('5', '西城区', '2018-05-22 09:58:03', '100', '1', '北京某地', '2018-06-22 16:41:51');INSERT INTO `air_quality_index` VALUES ('6', '东城区', '2018-05-22 09:58:03', '22', '22', '山东某地222333', '2018-05-22 10:54:36');INSERT INTO `air_quality_index` VALUES ('7', '西城区', '2018-05-22 09:58:03', '22', '22', '天津某地', '2018-05-22 10:57:41');INSERT INTO `air_quality_index` VALUES ('8', '西城区', '2018-05-22 09:58:03', '122', '232', '山东222', '2018-05-22 10:58:59');INSERT INTO `air_quality_index` VALUES ('9', '0', '2018-05-22 09:58:03', '22', '22', '北京某地', '2018-05-22 11:26:42');INSERT INTO `air_quality_index` VALUES ('10', '西城区', '2018-05-22 09:58:03', '22', '22', '天津某地', '2018-06-22 16:42:17');INSERT INTO `air_quality_index` VALUES ('11', '西城区', '2018-05-22 09:58:03', '1', '22', '灵境胡同监测站', '2018-06-22 16:42:50');
三，application.yml的配置
server:#端口号 port: 8080spring:#模板引擎 thymeleaf: prefix: classpath:/templates/ mode: HTML5 cache: false#阿里的druid datasource: name: test url: jdbc:mysql:///exam_air username: root password: type: com.alibaba.druid.pool.DruidDataSource driver-class-name: com.mysql.jdbc.Driver filters: stat maxActive: 20 initialSize: 1 maxWait: 60000 minIdle: 1 timeBetweenEvictionRunsMillis: 60000 minEvictableIdleTimeMillis: 300000 validationQuery: select 'x' testWhileIdle: true testOnBorrow: false testOnReturn: false poolPreparedStatements: true maxOpenPreparedStatements: 20mybatis: #映射的xml文件 mapper-locations: classpath:mapping/*.xml #别名 type-aliases-package: com.happy.entity
注意点：他是一种新的模板，yml不可以使用制表符TAB，它通过空格表示层级关系，同样的节点反复出现会有问题
我在里面配置了tomcat的端口，druid的数据源，以及mybatis的部分配置
四，项目骨架预览
五，thymeleaf模板的创建，他是以.html后缀名结尾的文件
1.主页面：
main.html
2.添加页面：
Title 添加空气质量信息
3.修改页面：
Title 空气质量信息维护页面
注意点：他是一种新的模板，与jsp写法有不同，展示数据的方式，引用js，css都不太一样，也不同与EL，JSTL，需要摸索
它的核心th
六，实体类
package cn.happy.entity;import cn.happy.util.JsonDateSerializer;import com.fasterxml.jackson.databind.annotation.JsonSerialize;import org.springframework.format.annotation.DateTimeFormat;import java.util.Date;public class AirModel { private Integer id; private String district; @DateTimeFormat(pattern = "yyyy-MM-dd hh:mm:ss") @JsonSerialize(using = JsonDateSerializer.class) /*处理日期格式*/ private Date monitorTime; private Integer pm10; private Integer pm25; private String monitoringStation; private Date createDate; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getDistrict() { return district; } public void setDistrict(String district) { this.district = district; } public Date getMonitorTime() { return monitorTime; } public void setMonitorTime(Date monitorTime) { this.monitorTime = monitorTime; } public Integer getPm10() { return pm10; } public void setPm10(Integer pm10) { this.pm10 = pm10; } public Integer getPm25() { return pm25; } public void setPm25(Integer pm25) { this.pm25 = pm25; } public String getMonitoringStation() { return monitoringStation; } public void setMonitoringStation(String monitoringStation) { this.monitoringStation = monitoringStation; } public Date getCreateDate() { return createDate; } public void setCreateDate(Date createDate) { this.createDate = createDate; }}
注意点：日期类型处理格式
@DateTimeFormat(pattern = "yyyy-MM-dd hh:mm:ss") @JsonSerialize(using = JsonDateSerializer.class) /*处理日期格式*/ private Date monitorTime;
七，工具类---就是处理日期格式的那个工具类
package cn.happy.util;import com.fasterxml.jackson.core.JsonGenerator;import com.fasterxml.jackson.core.JsonProcessingException;import com.fasterxml.jackson.databind.JsonSerializer;import com.fasterxml.jackson.databind.SerializerProvider;import java.io.IOException;import java.text.SimpleDateFormat;import java.util.Date;public class JsonDateSerializer extends JsonSerializer{ private SimpleDateFormat dateFormat=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); @Override public void serialize(Date date, JsonGenerator gen, SerializerProvider provider) throws IOException, JsonProcessingException { String value = dateFormat.format(date); gen.writeString(value); }}
八，Dao层
1.接口：
package cn.happy.mapper;import cn.happy.entity.AirModel;import java.util.List;import java.util.Map;public interface IAirDAO { //查询所有 public List findAll() throws Exception; //添加 public int addAir(AirModel model) throws Exception; //修改 public int updateAir(AirModel model) throws Exception; //按条件查询 public List findAirByCondition(Map map) throws Exception; //根据编号查询对象的方法 public AirModel selectOneById(Integer id) throws Exception;}
注意：他是一个普通的接口，没有注解是因为我在别处配置了一道，在yml有配置，在启动的那个main方法上面也有一道配置
2.dao层的xml
insert into air_quality_index(district,monitorTime,pm10,pm25,monitoringStation,createDate) values(#{district},#{monitorTime},#{pm10},#{pm25},#{monitoringStation},now()) update air_quality_index set district=#{district},monitorTime=#{monitorTime},pm10=#{pm10},pm25=#{pm25},monitoringStation=#{monitoringStation},createDate=now() where id=#{id}
注意：命名空间，别名
还有那个智能标签if test里面的写法
直接传的String类型他会报错，说没有getString的方法，所以用map往里传参数
假如test='address!=0'，他会报错，说不可以转换为数字，故写为test='address!="0"'即可
九，service层：
1.接口：
package cn.happy.service;import cn.happy.entity.AirModel;import java.util.List;public interface IAirService { //查询所有 public List findAll() throws Exception; //添加 public int addAir(AirModel model) throws Exception; //修改 public int updateAir(AirModel model) throws Exception; //按条件查询 public List findAirByCondition(String district) throws Exception; //根据编号查询对象的方法 public AirModel selectOneById(Integer id) throws Exception;}
2.实现类：
package cn.happy.service.impl;import cn.happy.entity.AirModel;import cn.happy.mapper.IAirDAO;import cn.happy.service.IAirService;import org.springframework.stereotype.Service;import org.springframework.transaction.annotation.Transactional;import javax.annotation.Resource;import java.util.HashMap;import java.util.List;import java.util.Map;@Service("airService")public class AirServiceImpl implements IAirService { @Resource(name = "IAirDAO") private IAirDAO dao; @Override public List findAll() throws Exception { return dao.findAll(); } @Override @Transactional public int addAir(AirModel model) { try { return dao.addAir(model); } catch (Exception e) { e.printStackTrace(); return 0; } } @Override public int updateAir(AirModel model) throws Exception { return dao.updateAir(model); } @Override public List findAirByCondition(String district) throws Exception { Map map=new HashMap (); map.put("district",district); return dao.findAirByCondition(map); } @Override public AirModel selectOneById(Integer id) throws Exception { return dao.selectOneById(id); }}
注意点：和普通的SSM注解开发没有什么太大的区别，值得注意的是事务的运用，需要在main那边开启一道配置
十，controller层：
package cn.happy.controller;import cn.happy.entity.AirModel;import cn.happy.service.IAirService;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 javax.annotation.Resource;import javax.validation.constraints.FutureOrPresent;import java.util.List;@Controllerpublic class FirstController { //植入Service @Resource(name = "airService") private IAirService myAirService; @RequestMapping("/goHome") public String getHome(){ return "main"; } @RequestMapping("/findAll") @ResponseBody public Object findAll() throws Exception { List list = myAirService.findAll(); return list; } @RequestMapping("/goAddPage") public String goAddPage(){ return "addAir"; } //添加数据 @RequestMapping("/addAir") public String addAir(AirModel model, Model modelData) throws Exception { int count = myAirService.addAir(model); if (count>0){ return "redirect:goHome"; }else{ modelData.addAttribute("erroMsg","添加失败"); return "redirect:goHome"; } } @RequestMapping("/goUpdatePage") @ResponseBody public Object goUpdatePage(int id) throws Exception { AirModel air = myAirService.selectOneById(id); return air; } @RequestMapping("/updateAir") public String updateAir(AirModel model) throws Exception { int count = myAirService.updateAir(model); return "redirect:goHome"; } //按条件查询 @RequestMapping("selectByCondition") @ResponseBody public Object selectByCondition(String district) throws Exception { List list = myAirService.findAirByCondition(district); return list; }}
普普通通，做过SSM的发现，没什么不同
十一，SpringBoot核心启动类的配置
package cn.happy;import org.mybatis.spring.annotation.MapperScan;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.transaction.annotation.EnableTransactionManagement;@SpringBootApplication//扫描mapper映射@MapperScan("cn.happy.*")/*开启事务*/@EnableTransactionManagementpublic class ExamApplication { public static void main(String[] args) { SpringApplication.run(ExamApplication.class, args); }}
注意点：开启事务和mybatis的扫描
十二，可以启动项目和调试了
注意：
我没仔细讲js，css，logback，logback就普通配置，无关紧要，css，js放在static下面即可，引入方式可以参考案例，我引用了一个bootstrap的js，这无关紧要，不影响，只需要jquery即可
