注: Eclipse rap 富客户端开发总结-系列文章是从本人   Iteye博客中移植过来.后续会直接在此更新     http://jlins.iteye.com/

1 、解决 rap 字符集乱码的问题

    字符集问题,解决办法:   在plugin.xml - build.properties 中添加

      javacDefaultEncoding.. = UTF-8   即可解决字符集乱码

2、解决web前台输入乱码问题

    使用传统的 字符集过滤器

    写一个过滤器类

<span style="font-size: small;">public class CharacterEncodingFilter implements Filter
{
private String edcoding;

private FilterConfig filterConfig;

private boolean ignore;

public CharacterEncodingFilter()

{
this.edcoding = null;

this.filterConfig = null;

this.ignore = true; }
public void destroy() {

this.edcoding = null;

this.filterConfig = null;

}

public void doFilter(ServletRequest request, ServletResponse response, FilterChain filterChain) throws IOException, ServletException

{

if ((this.ignore) || (request.getCharacterEncoding() == null)) {

String encoding = setCharacterEncoding(request);
if (encoding != null)

request.setCharacterEncoding(encoding)

}


filterChain.doFilter(request, response);

}



public void init(FilterConfig filterConfig) throws ServletException {
this.filterConfig = filterConfig;
this.edcoding = 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 String setCharacterEncoding(ServletRequest request)

{

return this.edcoding;

}

}

</span>


然后达成 jar 包方式到 war /WEB_INF/lib 目录下面

在 web.xml 添加

 

rap 导出 war 包时,编码问题处理,加入了字符过滤器的处理方式

1. 在导出 WAR 后,修改 war 包里面的 web.xml 文件,添加过滤器

内容如下

<span style="font-size: small;"><span>  <filter>          <filter-name>CharacterEncodingFilter</filter-name>          <filter-class>com.encoding.CharacterEncodingFilter</filter-class>          <init-param>              <param-name>encoding</param-name>              <param-value>UTF-8</param-value>          </init-param>      </filter>      <filter-mapping>          <filter-name>CharacterEncodingFilter</filter-name>          <url-pattern>/*</url-pattern>  </filter-mapping></span></span>


2. 增加 jar 包

   把过滤器要用的 jar 包【 encoding.jar 】添加到导出的 WAR 包的 lib 下面,这样     WAR 包加载后,能够找寻到过滤器用到的类。

 

上面 2 部分可以保证完美的解决中文问题
