‘driverName’ is not writable or has an invalid setter method. Does the
parameter type of the setter match the return type of the getter?

张冠李戴翻译过来就是:driverClassName 名笔者com.mchange.v2.c3p0.ComboPooledDataSource不认得,改个自小编认识的,不然小编罢工
解决:改名
driverClassName –>driverClass
url –>jdbcUrl
username –>user
password—>password

消除:因为pojo里的文件,xml的文书以及数据Curry的文书之间的映照有标题

Caused by: org.springframework.aop.framework.AopConfigException: Cannot
proxy target class because CGLIB2 is not available. Add CGLIB to the
class path or specify proxy interfaces.
缓解:恐怕jar包重复也或然不够cglib-2.1.3.jar

10.No result defined for action com.ssh.action.UserAction and result
success
解决:是Struts.xml配置难点

消除:是xxx.hbm.xml中<class name=”com.ssh.entity.User”
table=”user”>name中的路径应该是xxx实体类的门径,结果写到别的的实体类的门径了

赶尽杀绝:是xxx.hbm.xml中<class name=”com.ssh.entity.User”
table=”user”>name中的路径应该是xxx实体类的不二法门,结果写到别的的实体类的途径了

缓解:jsp中输出的id与实体类的eid差异<c:forEach items=”list”
var=”emp”>或然是<c:forEach items=”list”
var=”emp”>items中应有写成${list }
<td>${emp.id }</td>

Configuration problem: Unnamed bean definition specifies neither ‘class’
nor ‘parent’ nor ‘factory-bean’ – can’t generate bean name
Offending resource: class path resource [springmvc.xml]
化解:由于:bean
没有安插一体化,少了class等品质的铺排大概配置了空的bean<bean></bean>

18.java.lang.IllegalArgumentException: Expected
MultipartHttpServletRequest: is a MultipartResolver configured?
消除:这是因为找不到multipartReslover的因由,在springMVC配置文件配置它的时候,不可能用其余名字,只可以用钦点名字id=”multipartResolver”,否则就涌出那种找不到的失实。

18.java.lang.IllegalArgumentException: Expected
MultipartHttpServletRequest: is a MultipartResolver configured?
不留余地:那是因为找不到multipartReslover的原委,在springMVC配置文件配置它的时候,不可能用其余名字,只可以用钦定名字id=”multipartResolver”,不然就应运而生那种找不到的失实。

21.There is no Action mapped for namespace [/] and action name
[delete] associated with context path [/sshtest]. – [unknown
location]
缓解:Struts.xml中的action方法运用的是user_*的法子,在jsp页面中或任何请求中并未遵循user_*的主意呼吁,加上前缀user就足以了
