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-优快云博客

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

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; } }

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

<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>

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
