我在MySQL中有一个类型为decimal(3,2)的字段,只有当我输入类似78.3时,它似乎总是具有9.99的值.为什么？
这就是我的表格:
mysql> describe testtable;
+---------------+--------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+---------------+--------------+------+-----+---------+----------------+
| id | int(11) | NO | PRI | NULL | auto_increment |
| firstname | varchar(20) | YES | | NULL | |
| lastname | varchar(20) | YES | | NULL | |
| justsomenum | decimal(3,2) | YES | | NULL | |
+---------------+--------------+------+-----+---------+----------------+
当我插入这样的东西和选择:
mysql> insert into testtable (firstname, lastname, justsomenum) values ("Lloyd", "Christmas", 83.5);
我选择时得到9.99. …
我有什么应该是一个容易解决的问题,但我没有运气.
在我的servlet-servlet.xml文件中,我有以下bean(除了其他bean):
<bean id="viewResolver"
class="org.springframework.web.servlet.view.UrlBasedViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
<context:component-scan base-package="com.servlet.web" />
我的测试控制器看起来像这样:
package com.servlet.web;
import java.util.Map;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class TestController
{
protected final Log log = LogFactory.getLog(getClass());
@RequestMapping("/test")
public String methodName(Map<String, Object> map) {
map.put("someMessage", "some string here");
return "test";
}
}
我的jsp视图如下所示:
