对于spring-security来说,当你访问一个受保护资源时,需要检查你的token,当没有传递,或者传递的token有错误时,将出现401unauthorized异常;当你传递的token是有效的,但解析后并没有访问这个资源的权限时,将返回403forbidden的异常,而你通过拦截器@RestControllerAdvice
是不能重写这两个异常消息的,我们下面介绍重写这两种消息的方法。
两个接口
- AccessDeniedHandler 实现重写403的消息
- AuthenticationEntryPoint 实现重写401的消息
代码
- CustomAccessDeineHandler
public class CustomAccessDeineHandler implements AccessDeniedHandler {
@Override
public void handle(HttpServletRequest request, HttpServletResponse response,
AccessDeniedException accessDeniedException) throws IOException, ServletException {
response.setCharacterEncoding(\"utf-8\");
response.setContentType(\"application/json;charset=utf-8\");
response.getWriter().print(JSONObject.toJSONString(CommonResult.forbiddenFailure(\"没有访问权限!\")));
}
}
- CustomAuthenticationEntryPoint
public class CustomAuthenticationEntryPoint implements AuthenticationEntryPoint {
@Override
public void commence(HttpServletRequest request, HttpServletResponse response,
AuthenticationException authException) throws IOException, ServletException {
response.setCharacterEncoding(\"utf-8\");
response.setContentType(\"application/json;charset=utf-8\");
response.getWriter().print(JSONObject.toJSONString(CommonResult.unauthorizedFailure(\"需要先认证才能访问!\")));
}
}
- WebSecurityConfig.configure中添加注入代码
// 401和403自定义
http.exceptionHandling().authenticationEntryPoint(new CustomAuthenticationEntryPoint())
.accessDeniedHandler(new CustomAccessDeineHandler());
- 效果
//没有传token,或者token不合法
{
\"code\": 401,
\"message\": \"需要先认证才能访问!\"
}
//token中没有权限
{
\"code\": 403,
\"message\": \"没有访问权限!\"
}
