Maven+SSH整合记录
editor.clear()清除数据
https://blog.csdn.net/chengxu_hou/article/details/71747608
int id = (int) session.save(userEntity);的返回值一直是0
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "mid")
public int getMid() {
return mid;
}
或者
<id name="id" column="id">
<generator class="native">generator>
id>
乐观锁的问题 Row was updated or deleted by another transaction 异常的处理
session.save等类似的操作之后不要设置对象。
struts.xml文件中的method
- 如果不写method=xxx,他会直接返回result，不执行方法。所以要加上
- 如果一个action有多个方法，需要使用通配符的话，就需要使用
<allowed-methods>
login
allowed-methods>

加上事务aop后项目启动报错 BeanPostProcessor before instantiation of bean failed
在项目中加上基于xml的aop后，项目无法启动，错误信息如下：
Error creating bean with name ‘customerService’ defined in class path resource [bean.xml]: BeanPostProcessor before instantiation of bean failed;
原因是少了一个jar包：aspectj.weaver.jar

applicationContext.xml 配置文件的存放位置
web.xml中classpath:和classpath*: 有什么区别?
classpath：只会到你的class路径中查找找文件;
classpath*：不仅包含class路径，还包括jar文件中(class路径)进行查找.
存放位置：
1：src下面
需要在web.xml中定义如下：
<context-param>
<param-name>contextConfigLocationparam-name>
<param-value>classpath:applicationContext.xmlparam-value>
context-param>
2：WEB-INF下面
需要在web.xml中定义如下：
<context-param>
<param-name>contextConfigLocationparam-name>
<param-value>WEB-INF/applicationContext*.xmlparam-value>
context-param>
web.xml 通过contextConfigLocation配置spring 的方式
SSI框架配置文件路径问题：
struts2的 1个+N个 路径：src+src(可配置) 名称： struts.xml + N
spring 的 1个 路径： src 名称： applicationContext.xml
ibatis 的 1个+N个 路径： src+src(可配置) 名称： SqlMapConfig.xml + N
部署到tomcat后，src目录下的配置文件会和class文件一样，自动copy到应用的 classes目录下
spring的 配置文件在启动时，加载的是web-info目录下的applicationContext.xml,
运行时使用的是web-info/classes目录下的applicationContext.xml。
配置web.xml使这2个路径一致：
<context-param>
<param-name>contextConfigLocationparam-name>
<param-value>/WEB-INF/classes/applicationContext.xmlparam-value>
context-param>
多个配置文件的加载
<context-param>
<param-name>contextConfigLocationparam-name>
<param-value>
classpath*:conf/spring/applicationContext_core*.xml,
classpath*:conf/spring/applicationContext_dict*.xml,
classpath*:conf/spring/applicationContext_hibernate.xml,
classpath*:conf/spring/applicationContext_staff*.xml,
classpath*:conf/spring/applicationContext_security.xml
classpath*:conf/spring/applicationContext_modules*.xml
classpath*:conf/spring/applicationContext_cti*.xml
classpath*:conf/spring/applicationContext_apm*.xml
param-value>
context-param>
contextConfigLocation 参数定义了要装入的 Spring 配置文件。
首先与Spring相关的配置文件必须要以"applicationContext-"开头，要符合约定优于配置的思想，这样在效率上和出错率上都要好很多。
还有最好把所有Spring配置文件都放在一个统一的目录下，如果项目大了还可以在该目录下分模块建目录。这样程序看起来不会很乱。
在web.xml中的配置如下：
Xml代码
<context-param>
< param-name>contextConfigLocationparam-name>
< param-value>classpath*:**/applicationContext-*.xmlparam-value>
context-param>
"**/"表示的是任意目录；
"**/applicationContext-*.xml"表示任意目录下的以"applicationContext-"开头的XML文件。
你自己可以根据需要修改。最好把所有Spring配置文件都放在一个统一的目录下，如：
<context-param>
<param-name>contextConfigLocationparam-name>
<param-value>classpath:/spring/applicationContext-*.xmlparam-value>
context-param>
运行成功
