Spring security權(quán)限配置與使用大全

Spring Security 本質(zhì)上是借助一系列的 Servlet Filter來提供各種安全性功能，但這并不需要我們手動(dòng)去添加或者創(chuàng)建多個(gè)Filter，本文重點(diǎn)給大家介紹spring-security的配置與使用及實(shí)現(xiàn)方式，感興趣的朋友一起看看吧

簡介

Spring Security 是為了基于Spring的應(yīng)用程序提供的聲明式安全保護(hù)的安全性框架。Spring Security 提供了完整的安全性解決方案，它能夠在Web請(qǐng)求級(jí)別和方法調(diào)用級(jí)別處理身份認(rèn)證和授權(quán)。因?yàn)榛赟pring框架，所以SPring Security充分使用了一覽注入和面向切面技術(shù)。
Spring Security 本質(zhì)上是借助一系列的 Servlet Filter來提供各種安全性功能，但這并不需要我們手動(dòng)去添加或者創(chuàng)建多個(gè)Filter。實(shí)際上，我們僅需要配置一個(gè)Filter即可。
DelegatingFilterProxy 是一個(gè)特殊的Filter，他本身并沒有做太多工作，而是將工作委托給了一個(gè)注入到Spring應(yīng)用上下文的Filter實(shí)現(xiàn)類。

在本例中，主要講解spring-security的配置與使用，實(shí)現(xiàn)方式為：

　　　　1.將用戶、權(quán)限、資源（url）采用數(shù)據(jù)庫存儲(chǔ)

　　　　2.自定義過濾器，代替原有的 FilterSecurityInterceptor

　　　　3.自定義實(shí)現(xiàn) UserDetailsService、Filter、AccessDecisionManager和FilterInvocationSecurityMetadataSource并在配置文件進(jìn)行相應(yīng)的配置

　　　　4.Spring-seculity在自定義用戶驗(yàn)證的類加載必須早于Controller層創(chuàng)建

1.配置Spring-seculity.xml

<!--            </security:user-service>-->
        </security:authentication-provider>
    </security:authentication-manager>

</beans>

2.配置Web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

3.自定義用戶角色驗(yàn)證

package ssm.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.AuthorityUtils;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;
import ssm.bean.Role;
import ssm.bean.UserInfo;
import ssm.dao.LoginDao;

import java.util.ArrayList;
import java.util.List;

@Service("userinfo")
public class UserinfoService implements IUserInfoService{

    @Autowired
    LoginDao loginDao;

    @Override
    public UserDetails loadUserByUsername(String s) throws UsernameNotFoundException {　　　　//將s傳參從數(shù)據(jù)庫查詢是否用這個(gè)用戶
        UserInfo info=loginDao.findByList(s);
        List<Role> list=info.getRoles();
         List<GrantedAuthority> role= new ArrayList<GrantedAuthority>();
        for(Role i:list){
            role.add(new SimpleGrantedAuthority("ROLE_"+i.getRolename()));
        }

        System.out.println(s);
        return new User(info.getUsername(), "{noop}"+info.getPassword(),info.getStatus()!=0?true:false,true,true,true, role);


    }

}

4.seculity自定義過濾器

package filter;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.annotation.Order;
import org.springframework.security.access.SecurityMetadataSource;
import org.springframework.security.access.intercept.AbstractSecurityInterceptor;
import org.springframework.security.access.intercept.InterceptorStatusToken;
import org.springframework.security.web.FilterInvocation;

import org.springframework.security.web.access.intercept.FilterInvocationSecurityMetadataSource;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Service;

import javax.servlet.*;
import java.io.IOException;



@Service("myFilter")
public class MyFilter extends AbstractSecurityInterceptor implements Filter {

    @Autowired
    private FilterInvocationSecurityMetadataSource securityMetadataSource;

    @Override
    public Class<?> getSecureObjectClass() {
        return FilterInvocation.class;
    }

    @Override
    public SecurityMetadataSource obtainSecurityMetadataSource() {
        return securityMetadataSource;
    }

    @Autowired
    public void setMyAccessDecisionManager(MyAccessDescisionManager myAccessDescisionManager) {
        super.setAccessDecisionManager(myAccessDescisionManager);
    }
    @Override
    public void init(FilterConfig filterConfig) throws ServletException {

    }
    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {
        System.out.println("------------MyFilterSecurityInterceptor.doFilter()-----------開始攔截器了....");
        FilterInvocation fi = new FilterInvocation(request, response, chain);

        InterceptorStatusToken token = super.beforeInvocation(fi);

        try {
            fi.getChain().doFilter(fi.getRequest(), fi.getResponse());
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            super.afterInvocation(token, null);
        }

        System.out.println("------------MyFilterSecurityInterceptor.doFilter()-----------攔截器該方法結(jié)束了....");
    }

    @Override
    public void destroy() {

    }
}

5.自定義用戶權(quán)限驗(yàn)證

package filter;

import org.springframework.security.access.AccessDecisionManager;
import org.springframework.security.access.AccessDeniedException;
import org.springframework.security.access.ConfigAttribute;
import org.springframework.security.authentication.InsufficientAuthenticationException;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Service;

import java.util.Collection;
import java.util.Iterator;

@Service
public class MyAccessDescisionManager implements AccessDecisionManager {
 
    @Override
    public void decide(Authentication authentication, Object object, Collection<ConfigAttribute> configAttributes)throws AccessDeniedException, InsufficientAuthenticationException {
        // TODO Auto-generated method stub
         System.out.println("MyAccessDescisionManager.decide()------------------驗(yàn)證用戶是否具有一定的權(quán)限--------");  
            if(configAttributes==null) return;  
            Iterator<ConfigAttribute> it = configAttributes.iterator();
            while(it.hasNext()){  
                String needResource = it.next().getAttribute();  
                //authentication.getAuthorities()  用戶所有的權(quán)限  
                for(GrantedAuthority ga:authentication.getAuthorities()){
                    System.out.println("ROLE_"+needResource);
                    System.out.println(ga.getAuthority());
                    if(("ROLE_"+needResource).equals(ga.getAuthority())){  
                        return;  
                    }  
                }  
            }  
            throw new AccessDeniedException("--------MyAccessDescisionManager：decide-------權(quán)限認(rèn)證失敗！");  
        
    }
 
    @Override
    public boolean supports(ConfigAttribute attribute) {
        // TODO Auto-generated method stub
        return true;
    }
 
    @Override
    public boolean supports(Class<?> clazz) {
        // TODO Auto-generated method stub
        return true;
    }
 
}
