利用SpringSecurity和JWT实现mymes认证和授权(二)_if (username != null && securitycontextholder.getc

SpringBoot整合SpringSecurity和JWT实现mymes认证和授权(二)

接上一篇接上一篇，SpringSecurity的配置类相关依赖以及方法说明

• configure(HttpSecurity httpSecurity):用于拦截url路径、JWT过滤和异常处理

• configure(AuthenticationManagerBuilder auth):用于配置userDetailsService和PasswordEncoder

• JwtAuthenticationTokenFilter:在用户名和密码前添加过滤器，若有token,会根据token自行登录

• RestfulAccessDeniedHandler:在用户没有访问权限的时候，返回JSON格式的处理结果

• RestAuthenticationEntryPoint:在token失效或者没有登录情况下，返回JSON格式处理结果

• PasswordEncoder：SpringSecurity定义的用于对密码进行编码及比对的接口，目前使用的是BCryptPasswordEncoder；

• IgnoreUrlsConfig:用于从application.yml中获取不需要安全保护的资源路径

• UserDetailsService:SpringSecurity核心接口，获取用户信息

添加IgnoreUrlsConfig

package com.cn.mymes.utils.config;/*

import lombok.Getter;
import lombok.Setter;
import org.springframework.boot.context.properties.ConfigurationProperties;
 
import java.util.ArrayList;
import java.util.List;
 
/**

 */
@Getter
@Setter
@ConfigurationProperties(prefix = "secure.ignored")
public class IgnoreUrlsConfig {
 
    private List<String> urls = new ArrayList<>();
 
}
 

在application.yml中配置下不需要安全保护的资源路径

secure:
  ignored:
    urls: #安全路径白名单

添加Token过滤器JwtAuthenticationTokenFilter

package com.cn.mymes.component;
 
import com.cn.mymes.utils.JwtTokenUtil;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.web.authentication.WebAuthenticationDetailsSource;
import org.springframework.web.filter.OncePerRequestFilter;
 
import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
/**
 *token登录过滤器
 *
 */
public class JwtAuthenticationTokenFilter extends OncePerRequestFilter {
    private static final Logger LOGGER = LoggerFactory.getLogger(JwtAuthenticationTokenFilter.class);
    @Autowired
    private UserDetailsService userDetailsService;
    @Autowired
    private JwtTokenUtil jwtTokenUtil;
    @Value("${jwt.tokenHeader}")
    private String tokenHeader;
    @Value("${jwt.tokenHead}")
    private String tokenHead;
 
    @Override
    protected void doFilterInternal(HttpServletRequest request,
                                    HttpServletResponse response,
                                    FilterChain chain) throws ServletException, IOException {
        String authHeader = request.getHeader(this.tokenHeader);
        if (authHeader != null && authHeader.startsWith(this.tokenHead)) {
            String authToken = authHeader.substring(this.tokenHead.length());// The part after "Bearer "
            String username = jwtTokenUtil.getUserNameFromToken(authToken);
            LOGGER.info("checking username:{}", username);
            if (username != null && SecurityContextHolder.getContext().getAuthentication() == null) {
                UserDetails userDetails = this.userDetailsService.loadUserByUsername(username);
                if (jwtTokenUtil.validateToken(authToken, userDetails)) {
                    UsernamePasswordAuthenticationToken authentication = new UsernamePasswordAuthenticationToken(userDetails, null, userDetails.getAuthorities());
                    authentication.setDetails(new WebAuthenticationDetailsSource().buildDetails(request));
                    LOGGER.info("authenticated user:{}", username);
                    SecurityContextHolder.getContext().setAuthentication(authentication);
                }
            }
        }
        chain.doFilter(request, response);
    }
}

添加无权访问时RestfulAccessDeniedHandler方法

package com.cn.mymes.component;
 
import cn.hutool.json.JSONUtil;
import com.cn.mymes.common.CommonResult;
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;
/**
 *在没有权限访问时，返回自定义JSON格式结果
 */
public class RestfulAccessDeniedHandler implements AccessDeniedHandler{
    @Override
    public void handle(HttpServletRequest request,
                       HttpServletResponse response,
                       AccessDeniedException e) throws IOException, ServletException {
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Cache-Control","no-cache");
        response.setCharacterEncoding("UTF-8");
        response.setContentType("application/json");
        response.getWriter().println(JSONUtil.parse(CommonResult.forbidden(e.getMessage())));
        response.getWriter().flush();
    }
}

添加未登录或者登录过期返回自定义结果的RestAuthenticationEntryPoint方法

package com.cn.mymes.component;
 
 
import cn.hutool.json.JSONUtil;
import com.cn.mymes.common.CommonResult;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.AuthenticationEntryPoint;
 
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
/**
 * 未登录或者登录过期时，返回自定义JSON格式
 */
public class RestAuthenticationEntryPoint implements AuthenticationEntryPoint {
    @Override
    public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException authException) throws IOException, ServletException {
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Cache-Control","no-cache");
        response.setCharacterEncoding("UTF-8");
        response.setContentType("application/json");
        response.getWriter().println(JSONUtil.parse(CommonResult.unauthorized(authException.getMessage())));
        response.getWriter().flush();
    }
}

添加SpringSecurity核心接口，获取用户信息

package com.cn.mymes.domain;
 
 
 
 
import com.cn.mymes.mgb.model.UmsAdmin;
import com.cn.mymes.mgb.model.UmsResource;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
 
import java.util.Collection;
import java.util.List;
import java.util.stream.Collectors;
 
/**
 * SpringSecurity核心，获取用户信息
 *
 */
public class AdminUserDetails implements UserDetails {
    private UmsAdmin umsAdmin;
    private List<UmsResource> resourceList;
    public AdminUserDetails(UmsAdmin umsAdmin, List<UmsResource> resourceList) {
        this.umsAdmin = umsAdmin;
        this.resourceList = resourceList;
    }
 
    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        //返回当前用户的角色
        return resourceList.stream()
                .map(role ->new SimpleGrantedAuthority(role.getId()+":"+role.getName()))
                .collect(Collectors.toList());
    }
 
    @Override
    public String getPassword() {
        return umsAdmin.getPassword();
    }
 
    @Override
    public String getUsername() {
        return umsAdmin.getUsername();
    }
 
    @Override
    public boolean isAccountNonExpired() {
        return true;
    }
 
    @Override
    public boolean isAccountNonLocked() {
        return true;
    }
 
    @Override
    public boolean isCredentialsNonExpired() {
        return true;
    }
 
    @Override
    public boolean isEnabled() {
        return umsAdmin.getStatus().equals(1);
    }
}
