项目集成spring security3.2.6

spring security3.2版本

最近项目要集成spring security进行权限控制，之前对于安全管理框架只是稍微有所了解，并没有实际应用，所以在这部分花了一些时间。简要记录下

几个重要类或方法
1、UsernamePasswordAuthenticationFilter

    public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException {
    }

2、AbstractUserDetailsAuthenticationProvider

    public Authentication authenticate(Authentication authentication) throws AuthenticationException {
    }

3、UserDetailsService

UserDetails loadUserByUsername(String var1) throws UsernameNotFoundException;

4、UsernamePasswordAuthenticationToken

public UsernamePasswordAuthenticationToken(Object principal, Object credentials, Collection<? extends GrantedAuthority> authorities) {
        super(authorities);
        this.principal = principal;
        this.credentials = credentials;
        super.setAuthenticated(true); // must use super, as we override
    }

还有认证成功或失败的两个处理类
AuthenticationSuccessHandler

void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response,
            Authentication authentication) throws IOException, ServletException;

AuthenticationFailureHandler

    void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response,
            AuthenticationException exception) throws IOException, ServletException;

项目之前已经实现了了验证码，所以必须重写UsernamePasswordAuthenticationFilter，在里面添加验证码的验证。需要注意提交的input标签的name必须是j_username和j_password，form表单的action地址必须为j_spring_security_check。当然也可以修改，可以去实现这个AbstractAuthenticationProcessingFilter类重写一下。然后就是authenticate(Authentication authentication)这个方法。实现AuthenticationProvider，在authenticate方法内对账户和密码进行验证。最后比较重要的就是loadUserByUsername这个方法，实现UserDetailsService，返回一个UserDetails，可以是框架自带的User类，也可以自定义一个实体类实现UserDetails。
补充：配置xml文件需要将重写filter、provider、userDetailsService等加到配置里面

double补充：项目非maven项目，附上jar包下载地址spring security3.2.6，注意下载时需要把相关依赖包一并下载下来
