spring boot+vue前后端分离设计开发方案，你连原理都还没弄明白

spring boot+vue前后端分离设计开发方案，你连原理都还没弄明白

解决第二个问题的方式是对vue的路由的路径做rewrite，交给router来处理，而不是springboot自己处理，rewrite时可以考虑路由的路径统一增加后最，然后在springboot中编写过滤拦截特定后缀来做请求转发交给vue的路由处理。如：

const router = new VueRouter({

mode: ‘history’,

base: __dirname,

routes: [

{

path: ‘/ui/first.vhtml’,

component: First

},

{

path: ‘/ui/second.vhtml’,

component: secondcomponent

}

]

})

后端拦截到带有vhtml的都交给router来处理，这种方式在后端写过滤器拦截后打包是完全可行的，但是前端开发的直接访问带后缀的路径会有问题。

另外一种方式是给前端的路由path统一加个前缀比如/ui，这时后端写过滤器匹配该前缀，也不会影响前端单独开发是的路由解析问题。过滤器参考如下：

public class RewriteFilter implements Filter {

public static final String REWRITE_TO = “rewriteUrl”;

public static final String REWRITE_PATTERNS = “urlPatterns”;

private Set urlPatterns = null;//配置url通配符

private String rewriteTo = null;

@Override

public void init(FilterConfig cfg) throws ServletException {

//初始化拦截配置

rewriteTo = cfg.getInitParameter(REWRITE_TO);

String exceptUrlString = cfg.getInitParameter(REWRITE_PATTERNS);

if (StringUtil.isNotEmpty(exceptUrlString)) {

urlPatterns = Collections.unmodifiableSet(

new HashSet<>(Arrays.asList(exceptUrlString.split(";", 0))));

} else {

urlPatterns = Collections.emptySet();

}

}

@Override

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

HttpServletRequest request = (HttpServletRequest) req;

String servletPath = request.getServletPath();

String context = request.getContextPath();

//匹配的路径重写

if (isMatches(urlPatterns, servletPath)) {

req.getRequestDispatcher(context+"/"+rewriteTo).forward(req, resp);

}else{

chain.doFilter(req, resp);

}

}

@Override

public void destroy() {

}

private boolean isMatches(Set patterns, String url) {

if(null == patterns){

return false;

}

for (String str : patterns) {

if (str.endsWith("/*")) {

String name = str.substring(0, str.length() - 2);

if (url.contains(name)) {

return true;

}

} else {

Pattern pattern = Pattern.compile(str);

if (pattern.matcher(url).matches()) {

return true;

}

}

}

return false;

}

}
