2018-5-16发布的3.8以及之前版本待办任务查询优化

优化代码位于/BIZ/SA/task/logic/code/dsrc/TaskUtils.java的getExecutorCondition
本次优化将like换成了=，充分利用SA_TASK_SEXECUTORFID索引提升待办任务的查询效率
后面如果使用过程中再次出现性能下降，只要检查一下SA_TASK_SEXECUTORFID的索引碎片，优化一下就会好了

5.2.7版本中修改如下：

	public static String getExecutorCondition(String alias, Collection<PersonMember> pms, boolean useAgentProcess){
	/*
		String result = "";
		List<String> items = new ArrayList<String>();
		for (PersonMember pm : pms){
			String item = "'" + pm.getFID() + "' like concat(" + alias + ".sExecutorFID, '%')";
			if (useAgentProcess){
				String agentProcess = pm.getAgentProcess();
				if (Utils.isNotEmptyString(agentProcess)){
					String agentProcessCondition = getAgentProcessCondition(alias, agentProcess);
					item = appendCondition(item, "and", agentProcessCondition);
				}
			}
			
			items.add(item);
		}
		
		if (items.isEmpty()){
			result = "1<>1";
		}else{
			for (String item : items){
				if (result.equals("")){
					result = item;
				}else{
					result = result + " or " + item;
				}
			}
			
			result = appendCondition(result, "and", alias + ".sExecutorFID like '/%'");
		}
		
		return result;
	*/
	
		String result = "";
		for (PersonMember pm : pms) {
			com.justep.system.opm.OrgNode org = pm;
			String psmFilter = "";
			while (org != null) {
				if (psmFilter.length() > 0) {
					psmFilter = psmFilter + " OR ";
				} 
				psmFilter = psmFilter + "(" + alias + ".sExecutorFID = '" + org.getFID() + "')";
				org = org.getParent();
			}
			
			if (useAgentProcess){
				String agentProcess = pm.getAgentProcess();
				if (Utils.isNotEmptyString(agentProcess)){
					String agentProcessCondition = getAgentProcessCondition(alias, agentProcess);
					psmFilter = "(" + psmFilter + ") AND (" + agentProcessCondition + ")";
				}
			}
			
			if (result.length() > 0) {
				result = result + " OR ";
			}
			result = result + "(" + psmFilter + ")";
		}
		if (result.length() == 0) {
			result = "1=1";
		}
		result = "(" + result + ")";
	}

5.3.8版本(5.3版本中都是通用的)中修改如下：

	public static String getExecutorCondition(String alias, Collection<PersonMember> pms, boolean useAgentProcess, Map<String, Object> vars){
		/*
		if (taskExecutorOnlyPerson()){
			return getExecutorConditionWithPerson(alias, pms, useAgentProcess, vars);
		}
		
		String result = "";
		List<String> items = new ArrayList<String>();
		int i = 0;
		for (PersonMember pm : pms){
			String var = "_efid" + i++;
			vars.put(var, pm.getFID());
			String item = ":" + var + " like concat(" + alias + ".sExecutorFID, '%')";
			if (useAgentProcess){
				String agentProcess = pm.getAgentProcess();
				if (Utils.isNotEmptyString(agentProcess)){
					String agentProcessCondition = getAgentProcessCondition(alias, agentProcess, vars);
					item += " and " + agentProcessCondition;
				}
			}
			
			items.add(item);
		}
		
		if (items.isEmpty()){
			result = "1<>1";
		}else{
			for (String item : items){
				if (result.equals("")){
					result = item;
				}else{
					result = result + " or " + item;
				}
			}
			
			result = "(" + result + ") and " +  alias + ".sExecutorFID like '/%' ";
		}

		return result;
		*/
		
		if (taskExecutorOnlyPerson()){
			return getExecutorConditionWithPerson(alias, pms, useAgentProcess, vars);
		}
		
		String result = "";
		for (PersonMember pm : pms) {
			com.justep.system.opm.OrgNode org = pm;
			String psmFilter = "";
			while (org != null) {
				if (psmFilter.length() > 0) {
					psmFilter = psmFilter + " OR ";
				} 
				psmFilter = psmFilter + "(" + alias + ".sExecutorFID = '" + org.getFID() + "')";
				org = org.getParent();
			}
			
			if (useAgentProcess){
				String agentProcess = pm.getAgentProcess();
				if (Utils.isNotEmptyString(agentProcess)){
					String agentProcessCondition = getAgentProcessCondition(alias, agentProcess, vars);
					psmFilter = "(" + psmFilter + ") AND (" + agentProcessCondition + ")";
				}
			}
			
			if (result.length() > 0) {
				result = result + " OR ";
			}
			result = result + "(" + psmFilter + ")";
		}
		if (result.length() == 0) {
			result = "1=1";

		return result;
