Security 自定义DaoAuthenticationProvider 实现手动验证

首先在WebSecurityConfiguration 加上

   protected void configure(AuthenticationManagerBuilder auth) throws Exception {
	    	auth.authenticationProvider(new LoginAuthenticationProvider(loginService));
	                 
	    }

loginService 是UserDetailsService的类

然后写

package com.eca.mind.devops.interceptor;

import java.util.ArrayList;
import java.util.Collection;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.springframework.security.authentication.BadCredentialsException;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.authentication.dao.DaoAuthenticationProvider;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
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.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.MessageDigestPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.crypto.password.Pbkdf2PasswordEncoder;
import org.springframework.security.crypto.scrypt.SCryptPasswordEncoder;
import org.springframework.stereotype.Component;

import com.eca.mind.devops.common.FastJsonUtils;
import com.eca.mind.devops.common.SpringTool;
import com.eca.mind.devops.dao.SFuncMapper;

import com.eca.mind.devops.model.SUser;

@Component 
public class LoginAuthenticationProvider extends DaoAuthenticationProvider {
	

    public LoginAuthenticationProvider(UserDetailsService userDetailsService) {
        super();
        // 这个地方一定要对userDetailsService赋值，不然userDetailsService是null (这个坑有点深)
        setUserDetailsService(userDetailsService);
        setPasswordEncoder(createDelegatingPasswordEncoder());
    	
    }
    protected void additionalAuthenticationChecks(UserDetails userDetails,
            UsernamePasswordAuthenticationToken authentication) throws AuthenticationException {
        if (authentication.getCredentials() == null) {
            throw new BadCredentialsException(
                    messages.getMessage("AbstractUserDetailsAuthenticationProvider.badCredentials", "Bad credentials"));
        }
        String presentedPassword = userDetails.getUsername()+authentication.getCredentials().toString();
        PasswordEncoder passwordEncoder =getPasswordEncoder();
        if (!passwordEncoder.matches(presentedPassword, userDetails.getPassword())) {
			logger.debug("Authentication failed: password does not match stored value");

			throw new BadCredentialsException(messages.getMessage(
					"AbstractUserDetailsAuthenticationProvider.badCredentials",
					"Bad credentials"));
		}
      
    }
    public static PasswordEncoder createDelegatingPasswordEncoder() {
    String encodingId = "SHA-256";
    Map<String, PasswordEncoder> encoders = new HashMap<>();
	encoders.put(encodingId, new BCryptPasswordEncoder());
	encoders.put("ldap", new org.springframework.security.crypto.password.LdapShaPasswordEncoder());
	encoders.put("MD4", new org.springframework.security.crypto.password.Md4PasswordEncoder());
	encoders.put("MD5", new org.springframework.security.crypto.password.MessageDigestPasswordEncoder("MD5"));
	encoders.put("noop", org.springframework.security.crypto.password.NoOpPasswordEncoder.getInstance());
	encoders.put("pbkdf2", new Pbkdf2PasswordEncoder());
	encoders.put("scrypt", new SCryptPasswordEncoder());
	encoders.put("SHA-1", new org.springframework.security.crypto.password.MessageDigestPasswordEncoder("SHA-1"));
	encoders.put("SHA-256", new org.springframework.security.crypto.password.MessageDigestPasswordEncoder("SHA-256"));
	encoders.put("sha256", new org.springframework.security.crypto.password.StandardPasswordEncoder());

	return new MessageDigestPasswordEncoder("SHA-256");
}

}
