AuthenticationEntryPoint 用来解决匿名用户访问无权限资源时的异常

AccessDeineHandler 用来解决认证过的用户访问无权限资源时的异常

配置类：在资源服务器中配置

@Configuration
@EnableResourceServer // 开启资源服务器
@EnableGlobalMethodSecurity(prePostEnabled = true)
@Order(6)
public class ResourceServerConfiguration extends ResourceServerConfigurerAdapter {

    @Autowired
    private RedisConnectionFactory redisConnectionFactory;

    @Bean
    public TokenStore tokenStore() {
        // 基于 JDBC 实现，令牌保存到数据库
        //return new JdbcTokenStore(dataSource);
        // 基于redis 实现， 令牌保存到redis
        return new RedisTokenStore(redisConnectionFactory);
    }

    @Bean
    MyAuthenticationEntryPoint myAuthenticationEntryPoint() {
        return new MyAuthenticationEntryPoint();
    }

    @Bean
    MyAccessDeniedHandler myAccessDeniedHandler() {
        return new MyAccessDeniedHandler();
    }

    @Override
    public void configure(HttpSecurity http) {
        // 省略
    }

    @Override
    public void configure(ResourceServerSecurityConfigurer resource) {
        //这里把自定义异常加进去
        resource.tokenStore(tokenStore).authenticationEntryPoint(myAuthenticationEntryPoint())
                .accessDeniedHandler(myAccessDeniedHandler());
    }
}

之后，自定义AuthenticationEntryPoint的实现类:

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.AuthenticationEntryPoint;

import com.alibaba.fastjson.JSONObject;
import com.panku.common.domain.RestMsg;

public class CustomAuthenticationEntryPoint implements AuthenticationEntryPoint {

    @Override
    public void commence(HttpServletRequest request, HttpServletResponse response,
            AuthenticationException authException) throws IOException, ServletException {
        response.setCharacterEncoding("utf-8");
        response.setContentType("text/javascript;charset=utf-8");
        response.getWriter().print(JSONObject.toJSONString(RestMsg.error("没有访问权限!")));
    }
}

自定义，AccessDeineHandler：

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.security.access.AccessDeniedException;
import org.springframework.security.web.access.AccessDeniedHandler;

import com.alibaba.fastjson.JSONObject;
import com.panku.common.domain.RestMsg;

public class CustomAccessDeineHandler implements AccessDeniedHandler {

    @Override
    public void handle(HttpServletRequest request, HttpServletResponse response,
            AccessDeniedException accessDeniedException) throws IOException, ServletException {
        response.setCharacterEncoding("utf-8");
        response.setContentType("text/javascript;charset=utf-8");
        response.getWriter().print(JSONObject.toJSONString(RestMsg.error("没有访问权限!")));
    }

}
