---------解决方法，是程序添加的Filter这个类出问题了----------

给出正确filter配置文件

// 这是正确的filter类，启动没有异常

package cn.my.filter;

import javax.servlet.*;

import javax.servlet.http.HttpServletResponse;

import java.io.IOException;

public class CrosFilter implements javax.servlet.Filter {

@Override

public void init(FilterConfig filterConfig) throws ServletException {

}

@Override

public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {

HttpServletResponse res = (HttpServletResponse)servletResponse;

// 允许所有域名跨域

res.addHeader("Access-Control-Allow-Origin","*");

res.setHeader("Access-Control-Allow-Credentials", "true");

res.addHeader("Access-Control-Allow-Methods","GET,POST,PUT,DELETE,OPTIONS");

res.setHeader("Access-Control-Max-Age", "3600");

res.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept, Access-Control-Allow-Headers, Authorization");

filterChain.doFilter(servletRequest,servletResponse);

}

@Override

public void destroy() {

}

}

下面的是错误的，大家可以把错误的代码拿去试试。

// 错误的代码

// 错误的代码

// 错误的代码

package cn.my.filter;

import org.springframework.context.annotation.Configuration;

import javax.servlet.*;

import javax.servlet.annotation.WebFilter;

import javax.servlet.http.HttpServletResponse;

import java.io.IOException;

@WebFilter(filterName = "CorsFilter ")

@Configuration

public class CrosFilter implements Filter {

@Override

public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {

HttpServletResponse response = (HttpServletResponse) res;

response.setHeader("Access-Control-Allow-Origin","*");

response.setHeader("Access-Control-Allow-Credentials", "true");

response.setHeader("Access-Control-Allow-Methods", "POST, GET, PATCH, DELETE, PUT");

response.setHeader("Access-Control-Max-Age", "3600");

response.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");

chain.doFilter(req, res);

}

}

只要把filter代码修改了，tomcat启动就没有任何问题。如果不改代码换机器环境，重启电脑，都是无法解决的。
