tomcat class nofound,spring mvc的get请求乱码处理
一、maven中classnotfound1.其实是jar包问题，maven默认会把jar包编译到target下面，而tomcat需要在WEB-INF目录下使用它，所以发现没有的问题
需要在pom.xml中配置
maven-compiler-plugin
1.6
1.6
UTF-8
src\main\webapp\WEB-INF\lib
二、解决springmvc的get乱码问题
1.post处理乱码是这样的
encodingFilter
org.springframework.web.filter.CharacterEncodingFilter
true
encoding
UTF-8
encodingFilter
/*
2.get乱码处理
public class EncodingFilter extends OncePerRequestFilter {
private String encoding;
public void setEncoding(String encoding) {
this.encoding = encoding;
}
@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain chain)
throws ServletException, IOException {
// 设置请求响应字符编码
request.setCharacterEncoding(encoding);
response.setCharacterEncoding(encoding);
// 传递给目标servlet或jsp的实际上是动态代理的对象，而不是原始的HttpServletRequest对象
request = (HttpServletRequest) Proxy.newProxyInstance(request.getClass().getClassLoader(), request.getClass().getInterfaces(), new MyInvacationHandler(request));
chain.doFilter(request, response);
}
class MyInvacationHandler implements InvocationHandler{
private HttpServletRequest request;
MyInvacationHandler(HttpServletRequest request){
this.request=request;
}
@Override
public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
switch (method.getName()) {
case "getParameter":
String value = request.getParameter((String)args);
try {
if(value != null){
value=new String(value.getBytes("ISO-8859-1"),encoding);
}
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
return value;
case "getParameterValues":
String[] values = request.getParameterValues((String)args);
if (values != null) {
for (int i = 0; i < values.length; i++) {
try {
values = new String(values.getBytes("ISO-8859-1"),encoding);
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
}
}
return values;
default:
return method.invoke(request, args);
}
}
}
}
web.xml配置
encodingFilter12
com.wjw.controller.EncodingFilter
encoding
utf-8
encodingFilter12
/*
或者server.xml中配置
