項目集成spring security3.2.6

spring security3.2版本

最近項目要集成spring security進行權限控制，之前對於安全管理框架只是稍微有所瞭解，並沒有實際應用，所以在這部分花了一些時間。簡要記錄下

幾個重要類或方法
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
    }

還有認證成功或失敗的兩個處理類
AuthenticationSuccessHandler

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

AuthenticationFailureHandler

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

項目之前已經實現了了驗證碼，所以必須重寫UsernamePasswordAuthenticationFilter，在裏面添加驗證碼的驗證。需要注意提交的input標籤的name必須是j_username和j_password，form表單的action地址必須爲j_spring_security_check。當然也可以修改，可以去實現這個AbstractAuthenticationProcessingFilter類重寫一下。然後就是authenticate(Authentication authentication)這個方法。實現AuthenticationProvider，在authenticate方法內對賬戶和密碼進行驗證。最後比較重要的就是loadUserByUsername這個方法，實現UserDetailsService，返回一個UserDetails，可以是框架自帶的User類，也可以自定義一個實體類實現UserDetails。
補充：配置xml文件需要將重寫filter、provider、userDetailsService等加到配置裏面
