写在前面：本文采取的环境 1.docker下的mysql ，2.springboot(该demo采用mysql数据库，druid连接池，mybatis持久层)

项目地址：  
码云： https://gitee.com/belonghuang/dynamic-schedule  
github： https://github.com/Blankwhiter/dynamic-schedule

# 第一步 MySQL环境准备（可跳过） #

### 1.在centos窗口中，拉取mysql镜像，并且创建该容器： ###

docker pull mysql:5.7
    docker run --name test-mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.7

*注：等容器启动成功后，读者可以尝试用Navicat连接 ：账号root， 密码123456.*

### 2.数据库表准备，以及测试数据 ###

本人创建了名为**test**的数据库，并执行了下方语句创建表以及测试数据。

-- 定时任务
    CREATE TABLE `schedule_job` (
      `job_id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT '任务id',
      `bean_name` varchar(200) DEFAULT NULL COMMENT 'spring bean名称',
      `method_name` varchar(100) DEFAULT NULL COMMENT '方法名',
      `params` varchar(2000) DEFAULT NULL COMMENT '参数',
      `cron_expression` varchar(100) DEFAULT NULL COMMENT 'cron表达式',
      `status` tinyint(4) DEFAULT NULL COMMENT '任务状态  0：正常  1：暂停',
      `remark` varchar(255) DEFAULT NULL COMMENT '备注',
      `create_time` datetime DEFAULT NULL COMMENT '创建时间',
      PRIMARY KEY (`job_id`)
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='定时任务';
    
    -- 定时任务日志
    CREATE TABLE `schedule_job_log` (
      `log_id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT '任务日志id',
      `job_id` bigint(20) NOT NULL COMMENT '任务id',
      `bean_name` varchar(200) DEFAULT NULL COMMENT 'spring bean名称',
      `method_name` varchar(100) DEFAULT NULL COMMENT '方法名',
      `params` varchar(2000) DEFAULT NULL COMMENT '参数',
      `status` tinyint(4) NOT NULL COMMENT '任务状态    0：成功    1：失败',
      `error` varchar(2000) DEFAULT NULL COMMENT '失败信息',
      `times` int(11) NOT NULL COMMENT '耗时(单位：毫秒)',
      `create_time` datetime DEFAULT NULL COMMENT '创建时间',
      PRIMARY KEY (`log_id`),
      KEY `job_id` (`job_id`)
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='定时任务日志';
    
    INSERT INTO `schedule_job` (`bean_name`, `method_name`, `params`, `cron_expression`, `status`, `remark`, `create_time`) VALUES ('testTask', 'test', 'my-test', '0/10 * * * * ?', '0', '有参数测试', '2018-12-01 13:15:11');
    INSERT INTO `schedule_job` (`bean_name`, `method_name`, `params`, `cron_expression`, `status`, `remark`, `create_time`) VALUES ('testTask', 'test2', NULL, '0/15 * * * * ?', '1', '无参数测试', '2018-12-03 14:45:12');

*注：上方语句分别创建了定时任务表，以及定时任务日志表，并且加入两条有参数（每隔10秒），无参数（每隔15秒）的两个定时器*

# 第二步 编写项目 #

            </plugins>
        </build>
    
    </project>

### 2.配置项目环境 application.properties ###

server.port=8888
    #数据库设置
    spring.datasource.driverClassName=com.mysql.jdbc.Driver
    spring.datasource.url=jdbc:mysql://47.99.200.71:3306/test?allowMultiQueries=true&useUnicode=true&characterEncoding=utf8&autoReconnect=true&useSSL=true
    spring.datasource.username=root
    spring.datasource.password=123456
    #--------------------------
    # 下面为连接池的补充设置，应用到上面所有数据源中
    # 初始化大小，最小，最大
    spring.datasource.initialSize=5
    spring.datasource.minIdle=1
    spring.datasource.maxActive=50
    # 配置获取连接等待超时的时间
    spring.datasource.maxWait=60000
    # 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒
    spring.datasource.timeBetweenEvictionRunsMillis=60000
    # 配置一个连接在池中最小生存的时间，单位是毫秒
    spring.datasource.minEvictableIdleTimeMillis=300000
    spring.datasource.validationQuery=SELECT 1 FROM DUAL
    spring.datasource.testWhileIdle=true
    spring.datasource.testOnBorrow=false
    spring.datasource.testOnReturn=false
    # 打开PSCache，并且指定每个连接上PSCache的大小
    spring.datasource.poolPreparedStatements=false
    #spring.datasource.maxPoolPreparedStatementPerConnectionSize=20
    # 配置监控统计拦截的filters，去掉后监控界面sql无法统计，'wall'用于防火墙
    spring.datasource.filters=stat,wall,log4j
    # 通过connectProperties属性来打开mergeSql功能；慢SQL记录
    spring.datasource.connectionProperties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000
    # 合并多个DruidDataSource的监控数据
    #spring.datasource.useGlobalDataSourceStat=true
    
    
    mybatis.mapper-locations=classpath:mappers/*Mapper.xml
    mybatis.type-aliases-package=com.example.dynamicschedule.bean
    mybatis.check-config-location=true
    mybatis.config-location=classpath:mybatis-config.xml

### 3.启动上配置**MapperScan**注解,以及编写mybatis-config.xml ###

1.DynamicScheduleApplication.java

package com.example.dynamicschedule;
    
    import org.mybatis.spring.annotation.MapperScan;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    @SpringBootApplication
    @MapperScan(basePackages = "com.example.dynamicschedule.dao")
    public class DynamicScheduleApplication { 
    
        public static void main(String[] args) { 
            SpringApplication.run(DynamicScheduleApplication.class, args);
        }
    
    }

2.mybatis-config.xml

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">
    <configuration>
        <properties>
            <property name="dialect" value="mysql"/>
        </properties>
        <settings>
            
            <setting name="mapUnderscoreToCamelCase" value="true"/>
            
            <setting name="cacheEnabled" value="true"/>
            
            <setting name="lazyLoadingEnabled" value="true"/>
            
            <setting name="multipleResultSetsEnabled" value="true"/>
            
            <setting name="useColumnLabel" value="true"/>
            
            <setting name="useGeneratedKeys" value="false"/>
            
            <setting name="defaultExecutorType" value="SIMPLE"/>
            
            <setting name="defaultStatementTimeout" value="25000"/>
    
            <setting name="callSettersOnNulls" value="true"/> 
    
            
             <setting name="logImpl" value="STDOUT_LOGGING" />
        </settings>
    
        
          <plugins>
              <plugin interceptor="com.github.pagehelper.PageHelper">
                  
                  <property name="dialect" value="mysql" />
                  <property name="offsetAsPageNum" value="true" />
                  
                  <property name="rowBoundsWithCount" value="true" />
                  <property name="pageSizeZero" value="true" />
                  <property name="reasonable" value="true" />
              </plugin>
          </plugins>
    </configuration>

### 4.由项目的**resources**的**generator**配置文件，通过pom下配置的工具**mybatis-generator-maven-plugin**生成对应 ###

bean目录下：
    ScheduleJobExample
    ScheduleJob
    ScheduleJobLog
    ScheduleJobLogExample
    dao目录下：
    ScheduleJobLogMapper
    ScheduleJobMapper
    mapper目录下：
    ScheduleJobLogMapper.xml
    ScheduleJobMapper.xml

*注：由于此步骤已经有本人实现，不再过多赘述，如有疑问请留言评论，晚间本人将进行解答*

### 5.编写基础的返回信息类，异常捕捉，工具类 ###

**base**目录下：  
1.Constant.java

package com.example.dynamicschedule.base;
    
    /** * 常量 */
    public class Constant { 
        /** * 任务调度参数key */
        public static final String JOB_PARAM_KEY = "JOB_PARAM_KEY";
        /** * 定时任务状态 * */
        /** * 正常 */
        public static final int NORMAL = 0;
        /** * 暂停 */
        public static final int PAUSE =1;
    }

2.ResultCode.java

package com.example.dynamicschedule.base;
    
    /** * 返回信息码 */
    public enum ResultCode { 
        SUCCESS(0, "操作成功"),
        FAIL(1, "操作失败,请联系管理员"),
        PARAM_ERROR(2, "参数值格式有误"),
        RESOURCE_INVALID(3, "资源无效"),
        TOKEN_INVALID(11, "授权码无效"),
        CUSTOM_ERRORDESC(99);
        ResultCode(int code, String errorDesc) { 
            Code = code;
            ErrorDesc = errorDesc;
        }
        ResultCode(int code) { 
            Code = code;
        }
        private int Code;
        private String ErrorDesc;
    
        public int getCode() { 
            return Code;
        }
    
        public void setCode(int code) { 
            Code = code;
        }
    
        public String getErrorDesc() { 
            return ErrorDesc;
        }
    
        public void setErrorDesc(String errorDesc) { 
            ErrorDesc = errorDesc;
        }
    }

3.ResultDTO.java

package com.example.dynamicschedule.base;
    
    
    import java.io.Serializable;
    
    
    /** * 返回数据格式 * */
    public class ResultDTO implements Serializable { 
    
    	private int code;
    
    	private String msg;
    
    	private Object data;
    
    	private int count;
    	public ResultDTO(ResultCode code, Object result) { 
    		this.code = code.getCode();
    		this.msg = code.getErrorDesc();
    		this.data = result;
    	}
    
    	public ResultDTO(ResultCode code, String errorDesc, Object result) { 
    		this.code = code.getCode();
    		this.msg = errorDesc;
    		this.data = result;
    	}
    
    	public ResultDTO(int code, String errorDesc, Object result) { 
    		this.code = code;
    		this.msg = errorDesc;
    		this.data = result;
    	}
    
    
    }

**exception**目录下：  
4.GenericException.java

package com.example.dynamicschedule.exception;
    
    /** * 自定义异常 * */
    public class GenericException extends RuntimeException { 
    	private static final long serialVersionUID = 1L;
    
        private String msg;
        private int code = 500;
    
        public GenericException(String msg) { 
    		super(msg);
    		this.msg = msg;
    	}
    
    	public GenericException(String msg, Throwable e) { 
    		super(msg, e);
    		this.msg = msg;
    	}
    
    	public GenericException(String msg, int code) { 
    		super(msg);
    		this.msg = msg;
    		this.code = code;
    	}
    
    	public GenericException(String msg, int code, Throwable e) { 
    		super(msg, e);
    		this.msg = msg;
    		this.code = code;
    	}
    
    	public String getMsg() { 
    		return msg;
    	}
    
    	public void setMsg(String msg) { 
    		this.msg = msg;
    	}
    
    	public int getCode() { 
    		return code;
    	}
    
    	public void setCode(int code) { 
    		this.code = code;
    	}
    
    
    }

5.GenericExceptionHandler.java

package com.example.dynamicschedule.exception;
    
    import com.example.dynamicschedule.base.ResultDTO;
    import com.example.dynamicschedule.utils.ResultUtils;
    import lombok.extern.slf4j.Slf4j;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.dao.DuplicateKeyException;
    import org.springframework.web.bind.annotation.ExceptionHandler;
