JSON Spring 安全 OAuth2 中的请求不工作 tomcat 9

Question

已关注 post 将请求更改为 json。

我的配置

过滤器：

@Component
@Order(value = Integer.MIN_VALUE)
public class JsonToUrlEncodedAuthenticationFilter implements Filter {

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException,
            ServletException {
        if (Objects.equals(request.getContentType(), "application/json") && Objects.equals(((RequestFacade) request).getServletPath(), "/oauth/token")) {
            InputStream is = request.getInputStream();
            ByteArrayOutputStream buffer = new ByteArrayOutputStream();

            int nRead;
            byte[] data = new byte[16384];

            while ((nRead = is.read(data, 0, data.length)) != -1) {
                buffer.write(data, 0, nRead);
            }
            buffer.flush();
            byte[] json = buffer.toByteArray();

            HashMap<String, String> result = new ObjectMapper().readValue(json, HashMap.class);
            HashMap<String, String[]> r = new HashMap<>();
            for (String key : result.keySet()) {
                String[] val = new String[1];
                val[0] = result.get(key);
                r.put(key, val);
            }

            String[] val = new String[1];
            val[0] = ((RequestFacade) request).getMethod();
            r.put("_method", val);

            HttpServletRequest s = new MyServletRequestWrapper(((HttpServletRequest) request), r);
            chain.doFilter(s, response);
        } else {
            chain.doFilter(request, response);
        }
    }

    @Override
    public void destroy() {
    }
}

请求包装器：

public class MyServletRequestWrapper extends HttpServletRequestWrapper {
    private final HashMap<String, String[]> params;

    public MyServletRequestWrapper(HttpServletRequest request, HashMap<String, String[]> params) {
        super(request);
        this.params = params;
    }

    @Override
    public String getParameter(String name) {
        if (this.params.containsKey(name)) {
            return this.params.get(name)[0];
        }
        return "";
    }

    @Override
    public Map<String, String[]> getParameterMap() {
        return this.params;
    }

    @Override
    public Enumeration<String> getParameterNames() {
        return new Enumerator<>(params.keySet());
    }

    @Override
    public String[] getParameterValues(String name) {
        return params.get(name);
    }
}

以上配置在 spring 嵌入式启动 tomcat 中有效。不幸的是，当我调试过滤器时，它在 tomcat 9.0.1 中不起作用，它获取一次值并通过它传递给 doFilter()，从那里再次循环，下次它得到错误

ERROR boot.web.support.ErrorPageFilter - Forwarding to error page from request[/oauth/token] due to exception [No content to map due to end-of-input]

由于 json 不存在第二个循环，但是当使用 springboot 时它不会进入第二个循环。

关于使其在 spring 引导以及独立 tomcat 中工作的任何建议。

Answer 1

The issue was Duplicate Filter registration for 'springSecurityFilterChain'

。 Spring 开机启动一次，我的代码也尝试注册 springSecurityFilterChain 手动扩展

AbstractSecurityWebApplicationInitializer.class

，这导致 trouble.After 删除它，它在 spring 引导和独立 tomcat 中工作。
