Eclipse rap 富客户端开发总结(8) - 发布到tomcat后解决rap编码和字符集的问题

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
