數(shù)據(jù)庫表部分

第3步：創(chuàng)建數(shù)據(jù)庫模式并填充數(shù)據(jù)

/* For Remember-Me token storage purpose */
CREATE TABLE persistent_logins (
    username VARCHAR(64) NOT NULL,
    series VARCHAR(64) NOT NULL,
    token VARCHAR(64) NOT NULL,
    last_used TIMESTAMP NOT NULL,
    PRIMARY KEY (series)
);


/*All User's gets stored in APP_USER table*/
create table APP_USER (
   id BIGINT NOT NULL AUTO_INCREMENT,
   sso_id VARCHAR(30) NOT NULL,
   password VARCHAR(100) NOT NULL,
   first_name VARCHAR(30) NOT NULL,
   last_name  VARCHAR(30) NOT NULL,
   email VARCHAR(30) NOT NULL,
   state VARCHAR(30) NOT NULL, 	
   PRIMARY KEY (id),
   UNIQUE (sso_id)
);
 
/* USER_PROFILE table contains all possible roles */  
create table USER_PROFILE(
   id BIGINT NOT NULL AUTO_INCREMENT,
   type VARCHAR(30) NOT NULL,
   PRIMARY KEY (id),
   UNIQUE (type)
);
 
/* JOIN TABLE for MANY-TO-MANY relationship*/   
CREATE TABLE APP_USER_USER_PROFILE (
    user_id BIGINT NOT NULL,
    user_profile_id BIGINT NOT NULL,
    PRIMARY KEY (user_id, user_profile_id),
    CONSTRAINT FK_APP_USER FOREIGN KEY (user_id) REFERENCES APP_USER (id),
    CONSTRAINT FK_USER_PROFILE FOREIGN KEY (user_profile_id) REFERENCES USER_PROFILE (id)
);

/* Populate USER_PROFILE Table */
INSERT INTO USER_PROFILE(type)
VALUES ('USER');

INSERT INTO USER_PROFILE(type)
VALUES ('ADMIN');

INSERT INTO USER_PROFILE(type)
VALUES ('DBA');

/* Populate one Admin User. We need only one user to demonstrate this example. You can add more as done in previous posts*/
INSERT INTO APP_USER(sso_id, password, first_name, last_name, email, state)
VALUES ('sam','abc125', 'Sam','Smith','samy@xyz.com', 'Active');

/* Populate JOIN Table */
INSERT INTO APP_USER_USER_PROFILE (user_id, user_profile_id)
  SELECT user.id, profile.id FROM app_user user, user_profile profile
  where user.sso_id='sam' and profile.type='ADMIN';

安全部分

第4步：添加 Spring Security 配置類

package com.yiibai.springsecurity.configuration;

import javax.sql.DataSource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.web.authentication.rememberme.JdbcTokenRepositoryImpl;
import org.springframework.security.web.authentication.rememberme.PersistentTokenRepository;

@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

	@Autowired
	@Qualifier("customUserDetailsService")
	UserDetailsService userDetailsService;
	
	@Autowired
	DataSource dataSource;
	
	@Autowired
	public void configureGlobalSecurity(AuthenticationManagerBuilder auth) throws Exception {
		auth.userDetailsService(userDetailsService);
	}
	
	@Override
	protected void configure(HttpSecurity http) throws Exception {
	  http.authorizeRequests()
	  	.antMatchers("/", "/home").permitAll()
	  	.antMatchers("/admin/**").access("hasRole('ADMIN')")
	  	.antMatchers("/db/**").access("hasRole('ADMIN') and hasRole('DBA')")
	  	.and().formLogin().loginPage("/login")
	  	.usernameParameter("ssoId").passwordParameter("password")
	  	.and().rememberMe().rememberMeParameter("remember-me").tokenRepository(persistentTokenRepository()).tokenValiditySeconds(86400)
	  	.and().csrf()
	  	.and().exceptionHandling().accessDeniedPage("/Access_Denied");
	  	
	}
	
	@Bean
	public PersistentTokenRepository persistentTokenRepository() {
		JdbcTokenRepositoryImpl tokenRepositoryImpl = new JdbcTokenRepositoryImpl();
		tokenRepositoryImpl.setDataSource(dataSource);
		return tokenRepositoryImpl;
	}
}

第5步：使用war注冊(cè)springSecurityFilter

package com.yiibai.springsecurity.configuration;

import org.springframework.security.web.context.AbstractSecurityWebApplicationInitializer;

public class SecurityWebApplicationInitializer extends AbstractSecurityWebApplicationInitializer {

}

以上配置以XML配置格式為：

<filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>

<filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

第6步：定義UserDetailsService實(shí)現(xiàn)

package com.yiibai.springsecurity.service;

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

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
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 org.springframework.transaction.annotation.Transactional;

import com.yiibai.springsecurity.model.User;
import com.yiibai.springsecurity.model.UserProfile;

@Service("customUserDetailsService")
public class CustomUserDetailsService implements UserDetailsService{

	@Autowired
	private UserService userService;
	
	@Transactional(readOnly=true)
	public UserDetails loadUserByUsername(String ssoId)
			throws UsernameNotFoundException {
		User user = userService.findBySso(ssoId);
		System.out.println("User : "+user);
		if(user==null){
			System.out.println("User not found");
			throw new UsernameNotFoundException("Username not found");
		}
			return new org.springframework.security.core.userdetails.User(user.getSsoId(), user.getPassword(), 
				 user.getState().equals("Active"), true, true, true, getGrantedAuthorities(user));
	}

	
	private List<GrantedAuthority> getGrantedAuthorities(User user){
		List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
		
		for(UserProfile userProfile : user.getUserProfiles()){
			System.out.println("UserProfile : "+userProfile);
			authorities.add(new SimpleGrantedAuthority("ROLE_"+userProfile.getType()));
		}
		System.out.print("authorities :"+authorities);
		return authorities;
	}
	
}

SpringMVC部分

第7步: 添加控制器

package com.yiibai.springsecurity.controller;

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

import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.web.authentication.logout.SecurityContextLogoutHandler;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
public class HelloWorldController {

	
	@RequestMapping(value = { "/", "/home" }, method = RequestMethod.GET)
	public String homePage(ModelMap model) {
		model.addAttribute("greeting", "Hi, Welcome to mysite");
		return "welcome";
	}

	@RequestMapping(value = "/admin", method = RequestMethod.GET)
	public String adminPage(ModelMap model) {
		model.addAttribute("user", getPrincipal());
		return "admin";
	}

	@RequestMapping(value = "/db", method = RequestMethod.GET)
	public String dbaPage(ModelMap model) {
		model.addAttribute("user", getPrincipal());
		return "dba";
	}

	@RequestMapping(value = "/Access_Denied", method = RequestMethod.GET)
	public String accessDeniedPage(ModelMap model) {
		model.addAttribute("user", getPrincipal());
		return "accessDenied";
	}

	@RequestMapping(value = "/login", method = RequestMethod.GET)
	public String loginPage() {
		return "login";
	}

	@RequestMapping(value="/logout", method = RequestMethod.GET)
	public String logoutPage (HttpServletRequest request, HttpServletResponse response) {
		Authentication auth = SecurityContextHolder.getContext().getAuthentication();
		if (auth != null){    
			new SecurityContextLogoutHandler().logout(request, response, auth);
		}
		return "redirect:/login?logout";
	}

	private String getPrincipal(){
		String userName = null;
		Object principal = SecurityContextHolder.getContext().getAuthentication().getPrincipal();

		if (principal instanceof UserDetails) {
			userName = ((UserDetails)principal).getUsername();
		} else {
			userName = principal.toString();
		}
		return userName;
	}


}

第8步: 添加 SpringMVC 配置類

package com.yiibai.springsecurity.configuration;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.yiibai.springsecurity")
public class HelloWorldConfiguration extends WebMvcConfigurerAdapter {
	
	@Bean(name="HelloWorld")
	public ViewResolver viewResolver() {
		InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
		viewResolver.setViewClass(JstlView.class);
		viewResolver.setPrefix("/WEB-INF/views/");
		viewResolver.setSuffix(".jsp");

		return viewResolver;
	}

    /*
     * Configure ResourceHandlers to serve static resources like CSS/ Javascript etc...
     *
     */
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/static/**").addResourceLocations("/static/");
    }
}

第9步: 添加初始化類

package com.yiibai.springsecurity.configuration;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class SpringMvcInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

	@Override
	protected Class<?>[] getRootConfigClasses() {
		return new Class[] { HelloWorldConfiguration.class };
	}
 
	@Override
	protected Class<?>[] getServletConfigClasses() {
		return null;
	}
 
	@Override
	protected String[] getServletMappings() {
		return new String[] { "/" };
	}

}

Hibernate配置部分

第10步: 創(chuàng)建Hibernate配置

import java.util.Properties;

import javax.sql.DataSource;

import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;

import org.springframework.jdbc.datasource.DriverManagerDataSource;
import org.springframework.orm.hibernate4.HibernateTransactionManager;
import org.springframework.orm.hibernate4.LocalSessionFactoryBean;
import org.springframework.transaction.annotation.EnableTransactionManagement;

@Configuration
@EnableTransactionManagement
@ComponentScan({ "com.yiibai.springsecurity.configuration" })
@PropertySource(value = { "classpath:application.properties" })
public class HibernateConfiguration {

    @Autowired
    private Environment environment;

    @Bean
    public LocalSessionFactoryBean sessionFactory() {
        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
        sessionFactory.setDataSource(dataSource());
        sessionFactory.setPackagesToScan(new String[] { "com.yiibai.springsecurity.model" });
        sessionFactory.setHibernateProperties(hibernateProperties());
        return sessionFactory;
     }
	
    @Bean
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName(environment.getRequiredProperty("jdbc.driverClassName"));
        dataSource.setUrl(environment.getRequiredProperty("jdbc.url"));
        dataSource.setUsername(environment.getRequiredProperty("jdbc.username"));
        dataSource.setPassword(environment.getRequiredProperty("jdbc.password"));
        return dataSource;
    }
    
    private Properties hibernateProperties() {
        Properties properties = new Properties();
        properties.put("hibernate.dialect", environment.getRequiredProperty("hibernate.dialect"));
        properties.put("hibernate.show_sql", environment.getRequiredProperty("hibernate.show_sql"));
        properties.put("hibernate.format_sql", environment.getRequiredProperty("hibernate.format_sql"));
        return properties;        
    }
    
    @Bean
    @Autowired
    public HibernateTransactionManager transactionManager(SessionFactory s) {
       HibernateTransactionManager txManager = new HibernateTransactionManager();
       txManager.setSessionFactory(s);
       return txManager;
    }
}

application.properties

jdbc.driverClassName = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://localhost:3306/yiibai
jdbc.username = myuser
jdbc.password = mypassword
hibernate.dialect = org.hibernate.dialect.MySQLDialect
hibernate.show_sql = true
hibernate.format_sql = true
