ssh框架境遇的难点总计

解决:<!– 配置hibernate映射文件 –>时<property
name=””>的值忘记写了

Offending resource: class path resource [applicationContext.xml]
Caused by:
org.springframework.beans.factory.parsing.BeanDefinitionParsingException:
Configuration problem: Tag ‘property’ must have a ‘name’ attribute
Offending resource: class path resource [澳门新萄京官方网站,applicationContext.xml]

13.Caused by: org.springframework.beans.factory.BeanCreationException:

org.springframework.beans.NotWritablePropertyException: Invalid property
‘sessionFactory’ of bean class [com.ssh.dao.impl.DeptDaoImpl]: Bean
property ‘sessionFactory’ is not writable or has an invalid setter
method. Does the parameter type of the setter match the return type of
the getter?
解决:没有依赖注入

file:/E:/JavaDeveleper/apache-tomcat-9.0.0.M22/webapps/shop/WEB-INF/classes/struts.xml:17:10
解决:Struts.xml配置文件中的action要写在package中

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

1.org.springframework.beans.factory.BeanCreationException: Error
creating bean with name ‘dataSource’ defined in class path resource
[applicationContext.xml]: Error setting property values; nested
exception is org.springframework.beans.NotWritablePropertyException:
Invalid property ‘driverName’ of bean class
[com.mchange.v2.c3p0.ComboPooledDataSource]: Bean property
‘driverName’ is not writable or has an invalid setter method. Does the
parameter type of the setter match the return type of the getter?

21.There is no Action mapped for namespace [/] and action name
[delete] associated with context path [/sshtest]. – [unknown
location]
解决:Struts.xml中的action方法使用的是user_*的方式,在jsp页面中或其他请求中没有按照user_*的方式请求,加上前缀user就可以了

4.Caused by: java.lang.ClassNotFoundException:
org.springframework.jdbc.datasource.TransactionAwareDataSourceProxy
解决:确少spring-jdbc-4.2.4.RELEASE.jar包

15.Caused by: org.hibernate.MappingException: Duplicate property mapping
of ename found in com.ssh.entity.Emp
解决:xxx.hbm.xml映射文件中有重复字段

解决:是xxx.hbm.xml中<class name=”com.ssh.entity.User”
table=”user”>name中的路径应该是xxx实体类的路径,结果写到其他的实体类的路径了

Caused by: org.springframework.beans.NotWritablePropertyException:
Invalid property ‘driverName’ of bean class
[com.mchange.v2.c3p0.ComboPooledDataSource]: Bean property
‘driverName’ is not writable or has an invalid setter method. Does the
parameter type of the setter match the return type of the getter?
错误翻译过来就是:driverClassName 名我
com.mchange.v2.c3p0.ComboPooledDataSource不认得,改个我认识的,不然我罢工
解决:改名
driverClassName –>driverClass
url –>jdbcUrl
username –>user
password—>password

3.Caused by: org.springframework.beans.PropertyBatchUpdateException;
nested PropertyAccessExceptions (1) are:
PropertyAccessException 1:
org.springframework.beans.MethodInvocationException: Property
‘dataSource’ threw exception; nested exception is
java.lang.NoClassDefFoundError:
org/springframework/jdbc/datasource/TransactionAwareDataSourceProxy
解决:<!– 配置事务 –>
<bean id=”transactionManager”
class=”org.springframework.orm.hibernate5.HibernateTransactionManager”>
<property name=”dataSource”
ref=”dataSource”></property>//这里不要用dataSource.改用sessionFactory
</bean>

16.HTTP Status 500 – not-null property references a null or transient
value : com.ssh.entity.Emp.esex; nested exception is
org.hibernate.PropertyValueException: not-null property references a
null or transient value : com.ssh.entity.Emp.esex
解决:是xxx.hbm.xml中的属性设置为不能为空,但是我前台表单中的数据填写为空了。

解决:jsp中输出的id与实体类的eid不一致<c:forEach items=”list”
var=”emp”>或者是<c:forEach items=”list”
var=”emp”>items中应该写成${list }
<td>${emp.id }</td>

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.
解决:可能jar包重复也可能缺少cglib-2.1.3.jar

解决:在service的类上加上@Transactional注解

18.java.lang.IllegalArgumentException: Expected
MultipartHttpServletRequest: is a MultipartResolver configured?
解决:这是因为找不到multipartReslover的原因,在springMVC配置文件配置它的时候,不能用其他名字,只能用指定名字id=”multipartResolver”,否则就出现这种找不到的错误。

14.严重: Servlet.service() for servlet [jsp] threw exception
javax.el.PropertyNotFoundException: Property [id] not found on type
[java.lang.String]

8.java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
解决:缺少mysql驱动jar包

19.java.lang.NoSuchMethodException:
com.opensymphony.xwork2.ActionSupport.listAll()
解决:spring.xml核心配置文件忘记配置给应类的Javabean实例化

7.Caused by: java.lang.ClassNotFoundException:
com.mchange.v2.ser.Indirector”
解决:缺少mchange-commons-java-0.2.3.4.jar

9.Could not load requested class : com.ssh.entity.User
解决:因为pojo里的文件,xml的文件以及数据库里的文件之间的映射有问题

java.lang.NoSuchMethodException: com.ssh.action.UserAction.save()

2.Caused by: java.lang.NoClassDefFoundError:
javax/transaction/SystemException
解决:确少geronimo-jta jar包

17.org.springframework.beans.factory.parsing.BeanDefinitionParsingException:
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]
解决:由于:bean
没有配置完整,少了class等属性的配置或者配置了空的bean<bean></bean>

解决:原因是缺少jar包:struts2-spring-plugin-2.1.8.jar或者清理缓存,project

11.Caused by: org.hibernate.hql.internal.ast.QuerySyntaxException: Emp
is not mapped [from Emp]
解决:applicationContext中没有加载*.hbm.xml映射文件
