1. 利用spring boot提供的工具(http://start.spring.io/)自动生成一个标准的spring boot项目架构
2. 因为这里我们是搭建spring boot+mybatis+quartz架构，故在pom.xml文件中配置相关依赖
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot</artifactId>
<version>1.5.8.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
<version>1.5.8.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<version>1.5.8.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>

<scope>test</scope>
</dependency>
<dependency>
<groupId>org.mybatis.spring.boot</groupId>

</dependency>

</dependencies>
3. spring boot的理念是做到零配置，所以这里没有web.xml,只有一个application.yml的配置，这个时配置数据源及mybatis的mapper扫描路径
spring:
datasource:
url: jdbc:mysql://192.168.253.128/scheduler?useUnicode=true&characterEncoding=utf-8&autoReconnect=true&autoReconnectForPools=true
username: sche
password: sche
# 使用druid数据源
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: 20
jobFactory:
type: com.gary.operation.jobdemo.demo1.MyJobFactory
mybatis:
mapper-locations: classpath:mapper/*.xml
type-aliases-package: com.hq.dispach.entity
4. 这些基本的配置完成之后项目的结构如下
这里static目录是存放HTML，JavaScript等前端代码的
5. Spring boot web是不需要部署在Tomcat下的，因为自带了Tomcat，只需要执行主程序Application的main方法就可以了。但需要做些重要的配置
package com.hq.dispach;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
@EnableAutoConfiguration
@MapperScan("com.hq.dispach.dao")
public class DispachApplication {
public static void main(String[] args) {
SpringApplication.run(DispachApplication.class, args);
}
}
这里的配置@SpringBootApplication是默认，注意第二个和第三个配置，如果缺少@MapperScan("com.hq.dispach.dao")配置则会出现dao无法注入到service的情况，如果@EnableAutoConfiguration缺少则会出现quartz任务调度里无法注入service，这里建议不管是什么应用程序都最好加上这个配置。
5. 接下来就是control，service，dao，mapper，scheduleTask的代码编写了
Control：
package com.hq.dispach.control;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.hq.dispach.entity.Sche;
import com.hq.dispach.service.ScheService;
@RestController
@RequestMapping("/scheControl")
public class ScheControl {
@Autowired
private ScheService scheService;
@GetMapping("/addSche/{name}/{password}")
public Sche findScheByNameAndPassword(@PathVariable("name") String name,
@PathVariable("password") String password) {
return scheService.findScheByNameAndPassword(name, password);
}
}
Sevice:
package com.hq.dispach.service;
import com.hq.dispach.entity.Sche;
public interface ScheService {
public Sche findScheByNameAndPassword(String name,String password);
public String test();
}
Service实现
package com.hq.dispach.service.impl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.hq.dispach.dao.ScheMapper;
import com.hq.dispach.entity.Sche;
import com.hq.dispach.service.ScheService;
@Service("scheService")
public class ScheServiceImpl implements ScheService{
@Autowired
private ScheMapper scheMapper;
public Sche findScheByNameAndPassword(String name, String password) {
return scheMapper.findScheByNameAndPassword(name, password);
}
public String test() {
return "schedules run";
}
}
Dao:
package com.hq.dispach.dao;
import org.apache.ibatis.annotations.Param;
import com.hq.dispach.entity.Sche;
public interface ScheMapper {
public Sche findScheByNameAndPassword(@Param("name") String name, @Param("password") String password);
}
Mapper:
<?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.hq.dispach.dao.ScheMapper">
<select id="findScheByNameAndPassword" resultType="com.hq.dispach.entity.Sche">
SELECT t.`age`,t.`department`,t.`gendar`,t.`id`,t.`name`,t.`password`
FROM sche t
WHERE t.`name`=#{name} AND t.`password`=#{password}
</select>
</mapper>
ScheduleTask：
package com.hq.dispach.schedule;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Configurable;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
import com.hq.dispach.service.ScheService;
@Component
@Configurable
@EnableScheduling
public class ScheduledTasks{
@Autowired
private ScheService scheService;
//每1分钟执行一次
@Scheduled(cron = "0 */1 * * * * ")
public void reportCurrentByCron(){
System.out.println(scheService.test());
}
}
Entity:
package com.hq.dispach.entity;
public class Sche {
private String id;
private String name;
private String password;
private String age;
private String department;
private String gendar;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getAge() {
return age;
}
public void setAge(String age) {
this.age = age;
}
public String getDepartment() {
return department;
}
public void setDepartment(String department) {
this.department = department;
}
public String getGendar() {
return gendar;
}
public void setGendar(String gendar) {
this.gendar = gendar;
}
}
