innerRuleProcessing类实现代码：

innerRuleProcessQueryBean.setLimitTime(5);
innerRuleProcessQueryBean.setExecuteStatus(0);
innerRuleProcessQueryBean.setExecuteTimes(3);
innerRuleProcessQueryBean.setModulus(modulus);
innerRuleProcessQueryBean.setRemainder(remainder);
List<InnerRuleProcess> innerRuleProcesseslist = innerRuleProcessService.getInnerRuleTodoList(innerRuleProcessQueryBean);

getInnerRuleTodoList方法：

/*** 获取定时任务所需的进件集合* @param innerRuleProcessQueryBean* @return*/@Overridepublic List<InnerRuleProcess> getInnerRuleTodoList(InnerRuleProcessQueryBean innerRuleProcessQueryBean) {return innerRuleProcessMapper.selectInnerRuleList(innerRuleProcessQueryBean);}

selectInnerRuleList mybatis xml：

<select id="selectInnerRuleList" resultMap="BaseResultMap"  parameterType="com.jzfq.rms.autoApprove.bean.InnerRuleProcessQueryBean">SELECT<include refid="Base_Column_List" />FROM inner_rule_process t WHERE 1=1<if test="executeStatus != null" >AND execute_status = #{executeStatus,jdbcType=BIGINT}</if><if test="executeTimes != null" >AND execute_times <= #{executeTimes,jdbcType=BIGINT}</if><if test="modulus != null and remainder != null">AND MOD(front_id, #{modulus}) = #{remainder}</if>ORDER BY t.`create_time`<if test="limitTime != null" >LIMIT #{limitTime,jdbcType=BIGINT}</if></select>

该功能当quartz调用job是 通过遍历线程组 指派给单个新起线程线程编号

sql：

select  *  from inner_rule_process where execute_status = 0 and execute_times <=3 and MOD(front_id,6) = 5;
