我自己写的中文乱码过滤器：TomcatFormFilter
package com.ssh.common;

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 TomcatFormFilter implements Filter {
// 接收字符编码
protected String encoding;

public TomcatFormFilter() {
}

public void init(FilterConfig filterConfig) throws ServletException {
// 从web.xml中读取encoding值
encoding = filterConfig.getInitParameter("encoding");
}

public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
if (request.getCharacterEncoding() == null && encoding != null) {
// 设置字符集
request.setCharacterEncoding(encoding);
}
// 继续执行
chain.doFilter(request, response);
}

public void destroy() {
}

}

jar包的版本过低或者冲突或者与其他jar引用的 版本不匹配
删除antlr_2.72.jar

java.lang.NoSuchMethodError，这是jar包中没这个方法吧。
