SSM-整合
SSM的整合，可以用一个xml就完事，但是这里还是分隔以下彼此业务
模板引擎使用Thymeleaf，如果不是Thymeleaf，改改视图解析器就好了。

web.xml
里面的CORS可以不用这么麻烦，这里完全可以省去，然后复制个配置类就直接OK，在我博客中有。

applicationContext.xml
事物这块也不用这么麻烦，推荐使用注解。
AOP这快也使用注解比较好。

SimpleCORSFilter.java
你如果上面在SpringMVC中配置了CORS，那就需要下面的类。注意你的包名要和上面配置中一致
public class SimpleCORSFilter implements Filter {
private boolean isCross = false;
@Override
public void init(FilterConfig filterConfig) throws ServletException {
String isCrossStr = filterConfig.getInitParameter("IsCross");
isCross = isCrossStr.equals("true") ? true : false;
System.out.println(isCrossStr);
}
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
if (isCross) {
HttpServletRequest httpServletRequest = (HttpServletRequest) request;
HttpServletResponse httpServletResponse = (HttpServletResponse) response;
System.out.println("拦截请求: " + httpServletRequest.getServletPath());
//设置允许跨域
httpServletResponse.setHeader("Access-Control-Allow-Origin", httpServletRequest.getHeader("Origin"));
httpServletResponse.setHeader("Access-Control-Allow-Origin", "*");
httpServletResponse.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
httpServletResponse.setHeader("Access-Control-Max-Age", "0");
httpServletResponse.setHeader("Access-Control-Allow-Headers", "Origin, No-Cache, X-Requested-With, If-Modified-Since, Pragma, Last-Modified, Cache-Control, Expires, Content-Type, X-E4M-With,userId,token");
httpServletResponse.setHeader("Access-Control-Allow-Credentials", "true");
httpServletResponse.setHeader("XDomainRequestAllowed", "1");
}
chain.doFilter(request, response);
}
@Override
public void destroy() {
isCross = false;
}
}
