SpringBoot 中 Spring Security 403 自定义返回消息

• 自定义处理类 CustomAccessDeniedHandler

import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.http.HttpStatus;
import org.springframework.http.MediaType;
import org.springframework.security.access.AccessDeniedException;
import org.springframework.security.web.access.AccessDeniedHandler;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

public class CustomAccessDeniedHandler implements AccessDeniedHandler {

    @Override
    public void handle(HttpServletRequest request, HttpServletResponse response, AccessDeniedException accessDeniedException) throws IOException, ServletException {
        response.setContentType(MediaType.APPLICATION_JSON_UTF8_VALUE);
        response.setStatus(HttpStatus.FORBIDDEN.value());
        response.getWriter().write(new ObjectMapper().writeValueAsString(new CustomResponse("Session Invalid", null)));
    }

    static class CustomResponse {
        private String message;
        private Object data;

        CustomResponse(String message, Object data) {
            this.message = message;
            this.data = data;
        }

        public String getMessage() {
            return message;
        }

        public void setMessage(String message) {
            this.message = message;
        }

        public Object getData() {
            return data;
        }

        public void setData(Object data) {
            this.data = data;
        }
    }
}

• 在Spring Security 配置中添加配置

import org.springframework.context.annotation.Bean;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.web.access.AccessDeniedHandler;

@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/",
                        "/index.html",
                        "/**/favicon.ico",
                        "/login",
                        "/logout",
                        "/index",
                        "/error")
                .permitAll();

        http.authorizeRequests()
                .anyRequest()
                .authenticated()
                .and()
                .exceptionHandling().accessDeniedHandler(accessDeniedHandler());
    }

    @Bean
    public AccessDeniedHandler accessDeniedHandler() {
        return new CustomAccessDeniedHandler();
    }
}

• 返回值

{"message":"Session Invalid","data":null}
