020-实现手机认证过滤器和登录后封装手机认证信息(SpringSecurity大型项目)

1.创建MobileAuthenticationFilter ，模仿 UsernamePasswordAuthenticationFilter 代码进行改造

2.按ctrl+n,搜索UsernamePasswordAuthenticationFilter

UsernamePasswordAuthenticationFilter是校验用户名密码的,

我们只要模仿它写一个校验手机号的就行了

3. 全部复制UsernamePasswordAuthenticationFilter的代码到MobileAuthenticationFilter

修改前源码

package com.cis.security.authentication.mobile;


import org.springframework.lang.Nullable;
import org.springframework.security.authentication.AuthenticationServiceException;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.authentication.AbstractAuthenticationProcessingFilter;
import org.springframework.security.web.util.matcher.AntPathRequestMatcher;
import org.springframework.util.Assert;

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

/**
 * 用于校验用户手机号是否允许通过认证
 */
public class MobileAuthenticationFilter  extends AbstractAuthenticationProcessingFilter {
    public static final String SPRING_SECURITY_FORM_USERNAME_KEY = "username";
    public static final String SPRING_SECURITY_FORM_PASSWORD_KEY = "password";
    private String usernameParameter = "username";
    private String passwordParameter = "password";
    private boolean postOnly = true;

    public UsernamePasswordAuthenticationFilter() {
        super(new AntPathRequestMatcher("/login", "POST"));
    }

    public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException {
        if (this.postOnly && !request.getMethod().equals("POST")) {
            throw new AuthenticationServiceException("Authentication method not supported: " + request.getMethod());
        } else {
            String username = this.obtainUsername(request);
            String password = this.obtainPassword(request);
            if (username == null) {
                username = "";
            }

            if (password == null) {
                password = "";
            }

            username = username.trim();
            UsernamePasswordAuthenticationToken authRequest = new UsernamePasswordAuthenticationToken(username, password);
            this.setDetails(request, authRequest);
            return this.getAuthenticationManager().authenticate(authRequest);
        }
    }

    @Nullable
    protected String obtainPassword(HttpServletRequest request) {
        return request.getParameter(this.passwordParameter);
    }

    @Nullable
    protected String obtainUsername(HttpServletRequest request) {
        return request.getParameter(this.usernameParameter);
    }

    protected void setDetails(HttpServletRequest request, UsernamePasswordAuthenticationToken authRequest) {
        authRequest.setDetails(this.authenticationDetailsSource.buildDetails(request));
    }

    public void setUsernameParameter(String usernameParameter) {
        Assert.hasText(usernameParameter, "Username parameter must not be empty or null");
        this.usernameParameter = usernameParameter;
    }

    public void setPasswordParameter(String passwordParameter) {
        Assert.hasText(passwordParameter, "Password parameter must not be empty or null");
        this.passwordParameter = passwordParameter;
    }

    public void setPostOnly(boolean postOnly) {
        this.postOnly = postOnly;
    }

    public final String getUsernameParameter() {
        return this.usernameParameter;
    }

    public final String getPasswordParameter() {
        return this.passwordParameter;
    }
}

修改构造器名字为MobileAuthenticationFilter

修改账号密码为获取手机号

修改html请求路径url

修改获取账号密码为获取手机号

模仿UsernamePasswordAuthenticationToken创建MobileAuthenticationToken

修改setDetails方法的UsernamePasswordAuthenticationToken为MobileAuthenticationToken

把账号密码替换成手机号

修改后源码

package com.cis.security.authentication.mobile;


import org.springframework.lang.Nullable;
import org.springframework.security.authentication.AuthenticationServiceException;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.authentication.AbstractAuthenticationProcessingFilter;
import org.springframework.security.web.util.matcher.AntPathRequestMatcher;
import org.springframework.util.Assert;

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

/**
 * 用于校验用户手机号是否允许通过认证
 */
public class MobileAuthenticationFilter  extends AbstractAuthenticationProcessingFilter {
    //html表单手机号的name属性名是:mobile
    private String mobileParameter = "mobile";
    private boolean postOnly = true;

    //修改html表单的请求路径url为:/mobile/form"
    public MobileAuthenticationFilter() {
        super(new AntPathRequestMatcher("/mobile/form", "POST"));
    }

    public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException {
        if (this.postOnly && !request.getMethod().equals("POST")) {
            throw new AuthenticationServiceException("Authentication method not supported: " + request.getMethod());
        } else {

            String mobile = obtainMobile(request);

            if (mobile == null) {
                mobile = "";
            }

            mobile = mobile.trim();

            MobileAuthenticationToken authRequest = new MobileAuthenticationToken(mobile);
            //UsernamePasswordAuthenticationToken authRequest = new UsernamePasswordAuthenticationToken(username, password);
            this.setDetails(request, authRequest);
            return this.getAuthenticationManager().authenticate(authRequest);
        }
    }

    /**
     * 从请求中获取手机号码
     */
    @Nullable
    protected String obtainMobile(HttpServletRequest request) {
        return request.getParameter(mobileParameter);
    }

    /**
     * 将 sessionID和hostname添加 到MobileAuthenticationToken
     */
    protected void setDetails(HttpServletRequest request,
                              MobileAuthenticationToken authRequest) {
        authRequest.setDetails(authenticationDetailsSource.buildDetails(request));
    }


    /**
     * 设置是否为post请求
     */
    public void setPostOnly(boolean postOnly) {
        this.postOnly = postOnly;
    }

    public String getMobileParameter() {
        return mobileParameter;
    }

    public void setMobileParameter(String mobileParameter) {
        this.mobileParameter = mobileParameter;
    }
}

4.创建MobileAuthenticationToken,模仿UsernamePasswordAuthenticationToken

修改前

package com.cis.security.authentication.mobile;

import org.springframework.security.authentication.AbstractAuthenticationToken;
import org.springframework.security.core.GrantedAuthority;

import java.util.Collection;

public class MobileAuthenticationToken extends AbstractAuthenticationToken {
    private static final long serialVersionUID = 520L;
    private final Object principal;
    private Object credentials;

    public UsernamePasswordAuthenticationToken(Object principal, Object credentials) {
        super((Collection)null);
        this.principal = principal;
        this.credentials = credentials;
        this.setAuthenticated(false);
    }

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

    public Object getCredentials() {
        return this.credentials;
    }

    public Object getPrincipal() {
        return this.principal;
    }

    public void setAuthenticated(boolean isAuthenticated) throws IllegalArgumentException {
        if (isAuthenticated) {
            throw new IllegalArgumentException("Cannot set this token to trusted - use constructor which takes a GrantedAuthority list instead");
        } else {
            super.setAuthenticated(false);
        }
    }

    public void eraseCredentials() {
        super.eraseCredentials();
        this.credentials = null;
    }
}

修改构造方法

修改账号密码为手机号

修改后源码

package com.cis.security.authentication.mobile;

import org.springframework.security.authentication.AbstractAuthenticationToken;
import org.springframework.security.core.GrantedAuthority;

import java.util.Collection;

public class MobileAuthenticationToken extends AbstractAuthenticationToken {
    private static final long serialVersionUID = 520L;
    // principal:认证前存的是手机号码,认证后存的是用户信息
    private final Object principal;

    /**
     * 认证之前使用的构造方法, 此方法会标识未认证
     *
     */
    public MobileAuthenticationToken(Object principal) {
        super((Collection)null);
        this.principal = principal; // 手机号码
        setAuthenticated(false); // 未认证
    }

    /**
     * 认证通过后,会重新创建MobileAuthenticationToken实例 ,来进行封装认证信息
     * @param principal 用户信息
     * @param authorities 权限资源
     */
    public MobileAuthenticationToken(Object principal, Collection<? extends GrantedAuthority> authorities) {
        super(authorities);
        this.principal = principal;//用户信息
        super.setAuthenticated(true); // 已认证
    }


    /**
     * 因为它是父类中的抽象方法,,所以要实现,这里是返回密码,没有密码,直接返回null即可
     * @return
     */
    @Override
    public Object getCredentials() {
        return null;
    }

    //获取用户信息,这里是返回用户信息
    public Object getPrincipal() {
        return this.principal;
    }

    //设置权限资源
    public void setAuthenticated(boolean isAuthenticated) throws IllegalArgumentException {
        if (isAuthenticated) {
            throw new IllegalArgumentException("Cannot set this token to trusted - use constructor which takes a GrantedAuthority list instead");
        } else {
            super.setAuthenticated(false);
        }
    }

    public void eraseCredentials() {
        super.eraseCredentials();
    }
}
