层代码量比较大,涉及的地方也比较多,考虑到文章过于庞大,所以分两篇写。
我们还是先从主要的
action
开始吧。
在
com.game.products.web.actions

ProductsAction
,这是一个

需要注意的是,这里的

交由

的

管理了。
打开

大家可能注意到了这里有个
Set Character Encoding
过滤器。我们需要在
com.game.commons
包中新建
SetCharacterEncodingFilter
类来过滤编码,类的代码如下:
package
com.game.commons;
import
java.io.IOException;
import
javax.servlet.Filter;
import
javax.servlet.FilterChain;
import
javax.servlet.FilterConfig;
import
javax.servlet.ServletException;
import
javax.servlet.ServletRequest;
import
javax.servlet.ServletResponse;
public
class
SetCharacterEncodingFilter
implements
Filter
{
protected
String encoding
=
null
;
protected
FilterConfig filterConfig
=
null
;
protected
boolean
ignore
=
true
;
public
void
init(FilterConfig filterConfig)
throws
ServletException
{
this
.filterConfig
=
filterConfig;
this
.encoding
=
filterConfig.getInitParameter(
"
encoding
"
);
String value
=
filterConfig.getInitParameter(
"
ignore
"
);
if
(value
==
null
)
this
.ignore
=
true
;
else
if
(value.equalsIgnoreCase(
"
true
"
))
this
.ignore
=
true
;
else
this
.ignore
=
false
;
}
public
void
doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
throws
IOException, ServletException
{
//
TODO 自动生成方法存根
if
(ignore
||
(request.getCharacterEncoding()
==
null
))
{
String encoding
=
selectEncoding(request);
if
(encoding
!=
null
)
request.setCharacterEncoding(encoding);
}
chain.doFilter(request, response);
}
public
void
destroy()
{
//
TODO 自动生成方法存根
this
.encoding
=
null
;
this
.filterConfig
=
null
;
}
protected
String selectEncoding(ServletRequest request)
{
return
(
this
.encoding);
}
}
为了项目的测试运行,我们还需要配置
log4j.properties
,这个文件放在
src
根目录下。代码如下:
log4j.rootLogger=info,console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.SimpleLayout
log4j.logger.com.wehave=DEBUG
# log4j.logger.org.springframework=DEBUG
# SqlMap logging configuration
# log4j.logger.com.ibatis=DEBUG
# log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=DEBUG
# log4j.logger.com.ibatis.common.jdbc.ScriptRunner=DEBUG
# log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapClientDelegate=DEBUG
log4j.logger.java.sql.Connection=DEBUG
# log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG
#log4j.logger.java.sql.ResultSet=DEBUG
#log4j.logger.javax.sql=DEBUG
这是一个简单的
log4j
配置方法,只是在后台打印出需要的数据。如果还有别的需求,可以参考这个文档:如何使用
Log4j
?
为了达到页面验证的目的,我们还需要使用到
struts
的验证框架。
在
struts-validator
中添加
validation.xml
。在这配置验证规则:
<!
DOCTYPE form-validation PUBLIC
"-//Apache Software Foundation//DTD Commons Validator Rules Configuration 1.0//EN"
"http://jakarta.apache.org/commons/dtds/validator_1_0.dtd"
>

</
field

<
field

depends

>
<

/>
</
field

<

depends

<

/>
</
field

<
field

depends

>
<
arg0
key
="errors.gamePrice"
/>
</
field
>
</
form
>
</
formset
>
</
form-validation
>
在同个目录下,添加
validator-rules.xml
,这个在
struts
开发包中有,只需要
copy
过来就可以用了。为了方便大家,我这里将里面配置代码粘贴出来:
<?
xml version="1.0" encoding="ISO-8859-1"
?>
<!
DOCTYPE form-validation PUBLIC
"-//Apache Software Foundation//DTD Commons Validator Rules Configuration 1.0//EN"
"http://jakarta.apache.org/commons/dtds/validator_1_0.dtd"

<!--
This file contains the default Struts Validator pluggable validator
definitions. It should be placed somewhere under /WEB-INF and

<plug-in className="org.apache.struts.validator.ValidatorPlugIn">

These are the default error messages associated with
each validator defined in this file. They should be
added to your projects ApplicationResources.properties

pluggable validators msg attributes in this file.
# Struts Validator Error Messages
errors.required={0} is required.
