springmvc+easyui实现界面控制quartz的暂停、恢复、修改、添加

1、把quartz的表达式信息放到数据库中：

package cn.edu.nuc.entity;

public class ScheduleJob {
	private Integer id;
	 /** 任务id */
    private String jobId;
      
    /** 任务名称 */
    private String jobName;
      
    /** 任务分组 */
    private String jobGroup;
      
    /** 任务状态 0禁用 1启用 2删除*/
    private int jobStatus;
      
    /** 任务运行时间表达式 */
    private String cronExpression;
      
    /** 任务描述 */
    private String desc;
    
	public Integer getId() {
		return id;
	}

	public void setId(Integer id) {
		this.id = id;
	}

	public String getJobId() {
		return jobId;
	}

	public void setJobId(String jobId) {
		this.jobId = jobId;
	}

	public String getJobName() {
		return jobName;
	}

	public void setJobName(String jobName) {
		this.jobName = jobName;
	}

	public String getJobGroup() {
		return jobGroup;
	}

	public void setJobGroup(String jobGroup) {
		this.jobGroup = jobGroup;
	}

	public int getJobStatus() {
		return jobStatus;
	}

	public void setJobStatus(int jobStatus) {
		this.jobStatus = jobStatus;
	}

	public String getCronExpression() {
		return cronExpression;
	}

	public void setCronExpression(String cronExpression) {
		this.cronExpression = cronExpression;
	}

	public String getDesc() {
		return desc;
	}

	public void setDesc(String desc) {
		this.desc = desc;
	}
	
	
	
	
	public ScheduleJob() {
        super();
    }
 
    public ScheduleJob(String jobId, String jobName, String jobGroup,
            int jobStatus, String cronExpression, String desc) {
        super();
        this.jobId = jobId;
        this.jobName = jobName;
        this.jobGroup = jobGroup;
        this.jobStatus = jobStatus;
        this.cronExpression = cronExpression;
        this.desc = desc;
    }
}
