一、代码
@WebServlet(urlPatterns={"/abc"})
public class CharsetController extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
req.setCharacterEncoding("utf-8");
resp.setCharacterEncoding("utf-8");
resp.setContentType("text/html,charset=utf-8");
PrintWriter writer = resp.getWriter();
writer.write("123abc一二三");
writer.flush();
writer.close();
}
}
页面显示结果: 123abc涓€浜屼笁
二、解决
@WebServlet(urlPatterns={"/abc"})
public class CharsetController extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
req.setCharacterEncoding("utf-8");
resp.setCharacterEncoding("utf-8");
resp.setContentType("text/html,charset=utf-8");
//这里添加
resp.setContentType("text/plain; charset=utf-8");
PrintWriter writer = resp.getWriter();
writer.write("123abc一二三");
writer.flush();
writer.close();
}
}
页面显示： 123abc一二三
三、尝试其他的方法
applicaiton.properties中添加：
server.servlet.encoding.enabled=true
server.servlet.encoding.charset=UTF-8
server.servlet.encoding.force=true
结果：还是一样
使用全局过滤器：
package com.example.demo.config; import org.springframework.core.annotation.Order; import org.springframework.stereotype.Component; import javax.servlet.*; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import java.io.IOException; @Order(-1) @Component public class CharsetFilter implements Filter { @Override public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
HttpServletRequest request=(HttpServletRequest)servletRequest; HttpServletResponse response=(HttpServletResponse)servletResponse; request.setCharacterEncoding("utf-8"); response.setCharacterEncoding("utf-8"); response.setContentType("text/html,charset=utf-8"); //添加 response.setContentType("text/plain; charset=utf-8"); filterChain.doFilter(request,response); }
}
