Springside动态组合条件搜索：No enum constant org.springside.modules.persistence.SearchFilter.Operator.GE

Springside项目做动态组合条件搜索时，出现如下错误:

很明显，不支持的操作符GE，查看我们的代码：

                                                <li><label>信息：</label> <input type="text"
							value="${searchParamsTemp['GTE_seedlingsbaseinfo.diameter']}"
							size="15" name="search_GE_seedlingsbaseinfo.diameter"
							id="diameter"></li>
						<li><label>信息：</label> <input type="text"
							value="${searchParamsTemp['GTE_seedlingsbaseinfo.mijing']}"
							size="15" name="search_GE_seedlingsbaseinfo.mijing" id="mijing"></li>
						<li><label>信息：</label> <input type="text"
							value="${searchParamsTemp['GTE_seedlingsbaseinfo.height']}"
							size="15" name="search_GE_seedlingsbaseinfo.height" id="height"></li>
						<li><label>信息：</label> <input type="text"
							value="${searchParamsTemp['GTE_seedlingsbaseinfo.crown']}"
							size="15" name="search_GE_seedlingsbaseinfo.crown" id="crown"></li>
						<li><label>信息：</label> <input type="text"
							value="${searchParamsTemp['GTE_seedlingsbaseinfo.offbarHeight']}"
							size="15" name="search_GE_seedlingsbaseinfo.offbarHeight"
							id="offbarHeight"></li>

，查看 SearchFilter 源码：

可以看到仅支持六种操作：EQ, LIKE, GT, LT, GTE, LTE

修改程序name命名即可！注意后台Controller保持一致！
