默认情况下，token过期或失效的返回内容如下
{
"error": "invalid_token",
"error_description": "6610c99d-505c-4f80-927c-a5d23c0e54cb"
}
因为当前对接需求，需要把默认的返回内容修改为
{
"code": 10003,
"msg": "token失效"
}
百思不得其解，准备放弃，请求大神的时候，找到了解决办法
直接干货
第一个类：无效token 异常重写
@Component
public class AuthExceptionEntryPoint implements AuthenticationEntryPoint {
private static final int UN_LOGIN = 10002;
private static final int INVALID_TOKEN = 10003;
@Override
public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException authException) throws ServletException {
Map<String, Object> map = new HashMap<>();
Throwable cause = authException.getCause();
if (cause instanceof InvalidTokenException) {
//401
map.put("code", INVALID_TOKEN);
map.put("msg", "无效的token");
} else {
//401
map.put("code", UN_LOGIN);
map.put("msg", "访问此资源需要完全的身份验证");
}
response.setContentType("application/json");
response.setStatus(HttpServletResponse.SC_OK);
try {
ObjectMapper mapper = new ObjectMapper();
mapper.writeValue(response.getOutputStream(), map);
} catch (Exception e) {
throw new ServletException();
}
}
第二个类：权限不足异常类重写
@Component
public class CustomAccessDeniedHandler implements AccessDeniedHandler {
private static final int UN_LOGIN = 10002;
@Override
public void handle(HttpServletRequest request, HttpServletResponse response, AccessDeniedException accessDeniedException) throws IOException {
response.setContentType("application/json;charset=UTF-8");
Map<String, Object> map = new HashMap<>();
map.put("code", UN_LOGIN);
map.put("msg", "权限不足");
ObjectMapper mapper = new ObjectMapper();
response.setContentType("application/json");
response.setStatus(HttpServletResponse.SC_OK);
response.getWriter().write(mapper.writeValueAsString(map));
}
}
关键配置，在资源配置类中，重写方法：
@Override
public void configure(ResourceServerSecurityConfigurer resources) throws Exception {
super.configure(resources);
resources
.authenticationEntryPoint(new AuthExceptionEntryPoint())
.accessDeniedHandler(new CustomAccessDeniedHandler());
}
大功告成，看看您的结果把
