相關配置和代碼
application.properties配置密碼
spring.security.user.name=admin
spring.security.user.password=123
創建自定義身份過濾類
在idea連按下shift鍵，搜索UsernamePasswordAuthenticationFilter類
進入后再按Ctrl+F12可以查看該類的所有方法
進入方法
我們只需要在request.getParameter（）那里重寫一下不就可以實現json登陸
重寫attemptAuthentication(HttpServletRequestrequest,HttpServletResponseresponse)方法
只需要復制父類的方法，多加一個判斷json的方法。就能同時支持key-value形式可json形式的參數了

public class MyAuthenticationFilter extends UsernamePasswordAuthenticationFilter { @Override public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException { if(!request.getMethod().equals("POST")){ throw new AuthenticationServiceException("Authentication method not supported" + request.getMethod()); } //說明是以json的形式傳遞參數 if (request.getContentType().equals(MediaType.APPLICATION_JSON_VALUE)) { String username = null; String password = null; //將傳入的json數據轉換成map再通過get("key")獲得 try { Map<String,String> map =new ObjectMapper().readValue(request.getInputStream(), Map.class); username = map.get("username"); password = map.get("password"); } catch (IOException e) { e.printStackTrace(); } if (username == null) { } if (password == null) { } username = username.trim(); UsernamePasswordAuthenticationToken authRequest = new UsernamePasswordAuthenticationToken(username, password); setDetails(request, authRequest); return this.getAuthenticationManager().authenticate(authRequest); } return super.attemptAuthentication(request, response); }} |
創建SecurityConfig配置類
注：自定義的過濾類和security原來那個表單登陸過濾設置是分開的
體現在filter.setFilterProcessesUrl（）和loginProcessingUrl
因此表單登陸和json登陸的，successHandler判斷也要分開寫，
一會下面有效果圖也可以印證這一點
