如下报错：

16:22:05.566 [http-nio-80-exec-12] ERROR 500.jsp - No enum constant org.springside.modules.persistence.SearchFilter.Operator.GE

at java.lang.Thread.run(Thread.java:745) [na:1.8.0_25]

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>

			// 过滤掉空值

			if (StringUtils.isBlank((String) value)) {
				continue;
			}

			// 拆分operator与filedAttribute
			String[] names = StringUtils.split(key, "_");
			if (names.length != 2) {
				throw new IllegalArgumentException(key + " is not a valid search filter name");
			}
			String filedName = names[1];
			Operator operator = Operator.valueOf(names[0]);

			// 创建searchFilter
			SearchFilter filter = new SearchFilter(filedName, operator, value);
			filters.put(key, filter);
		}

		return filters;
	}
}</strong><span style="color:#dcdcdc;">

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！
