ibatis错误,属性存在却报不存在的错误

类中部分代码:
private String sICustId;
public String getSICustId()
{ return sICustId; }
public void setSICustId(String sICustId)
{ this.sICustId = sICustId; }
配置文件部分代码:

TOMCAT启动报错:org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlMapClient' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Invocation of init method failed; nested exception is java.lang.RuntimeException: Error occurred. Cause: com.ibatis.common.xml.NodeletException: Error parsing XML. Cause: java.lang.RuntimeException: Error parsing XPath '/sqlMapConfig/sqlMap'. Cause: com.ibatis.common.xml.NodeletException: Error parsing XML. Cause: java.lang.RuntimeException: Error parsing XPath '/sqlMap/resultMap/result'.

[code="java"]
private String siCustId;
public String getSiCustId()
{ return siCustId; }
public void setSiCustId(String siCustId)
{ this.siCustId = siCustId; }
[/code]

[code="java"]


[/code]

应该是SI中i的大小写问题

[code="java"]

[/code]
注意是sICustId哦

[code="java"]
private String sICustId;

public String getSICustId()
{

return sICustId;
}
[/code]

取得变量名问题!
这样就不会有错了。
[code="java"]
private String siCustId;

public String getSICustId()
{

return siCustId;
}
[/code]

应该有个配置文件来加载这个bean的你找一下

变量名问题。

ibatis 中需要映射的对象的属性名的大小写不能是 xX... 这样的格式. 如: eMail.

Csdn user default icon

Ibatis中的一个“There is no READABLE property named 'uId' in class 'userinfoPo”错误

我在ibatis中有如下配置: 这是一个PO: /** * 用户基本信息 * @author Rao * @Date 2009-10-04 * @Table (mwweb.userinfo) */ public class UserinfoPo { private String uId; //用户Id private String uName; //用户登录名称 private String uNickname; //用户昵称 private String uPass; //用户密码 private String uEmail; //用户Email private String uBirth; //用户出生日期 private int uSex; //用户性别(1男,2女) private String uAddress; //用户地址 public String getUName() { return uName; } public void setUName(String name) { uName = name; } public String getUPass() { return uPass; } public void setUPass(String pass) { uPass = pass; } public String getUEmail() { return uEmail; } public void setUEmail(String email) { uEmail = email; } public String getUBirth() { return uBirth; } public void setUBirth(String birth) { uBirth = birth; } public int getUSex() { return uSex; } public void setUSex(int sex) { uSex = sex; } public String getUAddress() { return uAddress; } public void setUAddress(String address) { uAddress = address; } public String getUNickname() { return uNickname; } public void setUNickname(String nickname) { uNickname = nickname; } public String getUId() { return uId; } public void setUId(String id) { uId = id; } } 这是sqlMap中的userinfo.xml配置文件: <!-- 新增用户 --> <insert id="insertUserinfo" parameterClass="MWWeb.bbs.po.UserinfoPo"> <![CDATA[ INSERT INTO userinfo( uId, uName, uNickname, uPass, uEmail, uBirth, uSex, uAddress ) values ( #uId:VARCHAR#, #uName:VARCHAR#, #uNickname:VARCHAR#, #uPass:VARCHAR#, #uEmail:VARCHAR#, #uBirth:VARCHAR#, #uSex:INT#, #uAddress:VARCHAR#, ) ]]> </insert> 我部署好了启动tomcat时出现了这样的错误: There is no READABLE property named 'uId' in class 'MWWeb.bbs.po.UserinfoPo' 这是什么问题呢,我找了好久都没有解决。 希望各位达人能够给与指教,在下实在是感激不尽 [b]问题补充:[/b] 我又重新部署了,不是没有编译,部署了旧的.class文件

ibatis SQL Mapping

<statement id="getCustomersCount" resultClass="java.lang.Integer" parameterClass="java.util.Map"> <![CDATA[#countquery_sql#]]> </statement> SQL是从HashMap中取得的,可以吗 [b]问题补充:[/b] 谢谢 <statement id="getCustomers" resultClass="java.util.List" remapResults="true" resultMap="CustomerObject" parameterClass="java.util.Map" > <![CDATA[$query_sql$]]> </statement> 这样可以运行 但是resultMap="CustomerObject" 这个对象的属性 和 列的数量不一致 有列名无效的错误。 [b]问题补充:[/b] 怎么解决? [b]问题补充:[/b] 谢谢 关键是我想用ResultMap 因为我有些字段要用handler.

ssm+shiro查询数据库错误导致不能验证登录

ssm的时候没有问题,可是加了shiro之后问题不断 先是dao层定义的方法 ``` public User find(@Param("username") String username); ``` 然后是mapper.xml里对应的sql语句 ``` <select id="find" resultType="com.entity.User"> select password from user where username=#{username} </select> ``` User层定义了账号和密码两个属性,分别有get与set方法 service层到serviceImpl层的方法是 ``` public User findpassword(String username){ User user=userDao.find(username); return user; } ``` 自定义的MyRealm中的doGetAuthenticationInfo方法代码为 ``` @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException{ String username=(String)token.getPrincipal(); User user=ser.findpassword(username); if(user==null){ throw new UnknownAccountException(); } SimpleAuthenticationInfo info=new SimpleAuthenticationInfo(user.getUsername(),user.getPassword(),getName()); return info; } ``` controller层就不写了,就是调用了subject.login()方法 然后挂到tomcat运行,输入账号密码就会报错 ``` org.apache.shiro.authc.AuthenticationException: Authentication failed for token submission [org.apache.shiro.authc.UsernamePasswordToken - A2, rememberMe=false].

Spring加载**.properties失败的问题

小弟刚刚接触spring。打算自己建立一个工程。在创建过程中遇到一个问题,如下: 工程结构: ![图片说明](https://img-ask.csdn.net/upload/201801/09/1515501502_610362.png) web.xml引入子工程配置: ![图片说明](https://img-ask.csdn.net/upload/201801/09/1515501585_212136.png) mq-demo-consumer.xml里面引入文件配置如下: ![图片说明](https://img-ask.csdn.net/upload/201801/09/1515501673_779393.png) spring-config.xml里面引入配置文件如下: ![图片说明](https://img-ask.csdn.net/upload/201801/09/1515501740_742955.png) 其中spring-datasources.xml 文件引入: <context:property-placeholder location="classpath*:jdbc.properties"/> mq-inputpiece-api.xml文件引入: <context:property-placeholder location="classpath*:rabbitmq.properties"/> 所有的**.properties文件都在 ![图片说明](https://img-ask.csdn.net/upload/201801/09/1515501904_253256.png) 编译之后class文件: ![图片说明](https://img-ask.csdn.net/upload/201801/09/1515501978_905039.png) 可以看到所有的**.properties已经都在classes路径下。 具体问题是: web.xml的配置的 <context-param> <param-name>contextConfigLocation</param-name> <param-value> <!--classpath*:spring-config.xml,--> classpath*:mq-demo-consumer.xml, classpath*:spring-config.xml, <!--classpath*:spring-redis.xml,--> classpath*:spring-shiro.xml; </param-value> </context-param> 如果屏蔽mq-demo-consumer.xml则系统正常。如果引入mq-demo-consumer.xml则spring-config.xml里面配置的数据库问题提示找不到**.properties里面的配置项。如果把spring-config.xml 放到 mq-demo-consumer.xml之前则mq-demo-consumer.xml里面配置的mq-inputpiece-api.xml里面找不到rabbitmq.properties里面的配置项。查看spring加载日志发现只有写在web.xml里面前面的xml文件可以引入**.propert。后面的文件无法引入 **.xml里面配置的**.properties

删库了,我们一定要跑路吗?

在工作中,我们误删数据或者数据库,我们一定需要跑路吗?我看未必,程序员一定要学会自救,神不知鬼不觉的将数据找回。 在 mysql 数据库中,我们知道 binlog 日志记录了我们对数据库的所有操作,所以 binlog 日志就是我们自救的利器。 接下来就来开启程序员自救之路。 想要自救成功,binlog 这把利器一定要好,在自己之前,我们一定要确定我们有 binlog 这把利器,以下就是确保有 bi...

华为初面+综合面试(Java技术面)附上面试题

华为面试整体流程大致分为笔试,性格测试,面试,综合面试,回学校等结果。笔试来说,华为的难度较中等,选择题难度和网易腾讯差不多。最后的代码题,相比下来就简单很多,一共3道题目,前2题很容易就AC,题目已经记不太清楚,不过难度确实不大。最后一题最后提交的代码过了75%的样例,一直没有发现剩下的25%可能存在什么坑。 笔试部分太久远,我就不怎么回忆了。直接将面试。 面试 如果说腾讯的面试是挥金如土...

无代码时代来临,程序员如何保住饭碗?

编程语言层出不穷,从最初的机器语言到如今2500种以上的高级语言,程序员们大呼“学到头秃”。程序员一边面临编程语言不断推陈出新,一边面临由于许多代码已存在,程序员编写新应用程序时存在重复“搬砖”的现象。 无代码/低代码编程应运而生。无代码/低代码是一种创建应用的方法,它可以让开发者使用最少的编码知识来快速开发应用程序。开发者通过图形界面中,可视化建模来组装和配置应用程序。这样一来,开发者直...
