2 . 准备你的数据库，设计表结构，要用户使用登入登出，新建用户表。
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`user_uuid` varchar(70) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
`username` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
`password` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
`email` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
`telephone` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
`role` int(10) DEFAULT NULL,
`image` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
`last_ip` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
`last_time` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 2 CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Compact;
SET FOREIGN_KEY_CHECKS = 1;
3 . 用户对象User.java :
import javax.persistence.*;
/**
* Created by EalenXie on 2018/7/5 15:17
*/
@Entity
@Table(name = "USER")
public class User {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;
private String user_uuid; //用户UUID
private String username; //用户名
private String password; //用户密码
private String email; //用户邮箱
private String telephone; //电话号码
private String role; //用户角色
private String image; //用户头像
private String last_ip; //上次登录IP
private String last_time; //上次登录时间
public Integer getId() {
return id;
}
public String getRole() {
return role;
}
public void setRole(String role) {
this.role = role;
}
public String getImage() {
return image;
}
public void setImage(String image) {
this.image = image;
}
public void setId(Integer id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getTelephone() {
return telephone;
}
public void setTelephone(String telephone) {
this.telephone = telephone;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getUser_uuid() {
return user_uuid;
}
public void setUser_uuid(String user_uuid) {
this.user_uuid = user_uuid;
}
public String getLast_ip() {
return last_ip;
}
public void setLast_ip(String last_ip) {
this.last_ip = last_ip;
}
public String getLast_time() {
return last_time;
}
public void setLast_time(String last_time) {
this.last_time = last_time;
}
@Override
public String toString() {
return "User{" +
"id=" + id +
", user_uuid='" + user_uuid + '\'' +
", username='" + username + '\'' +
", password='" + password + '\'' +
", email='" + email + '\'' +
", telephone='" + telephone + '\'' +
", role='" + role + '\'' +
", image='" + image + '\'' +
", last_ip='" + last_ip + '\'' +
", last_time='" + last_time + '\'' +
'}';
}
} 4 . application.yml配置一些基本属性
spring:
resources:
static-locations: classpath:/
freemarker:
template-loader-path: classpath:/templates/
suffix: .html
content-type: text/html
charset: UTF-8
datasource:
url: jdbc:mysql://localhost:3306/yourdatabase
username: yourname
password: yourpass
driver-class-name: com.mysql.jdbc.Driver
type: com.alibaba.druid.pool.DruidDataSource
server:
port: 8083
error:
whitelabel:
enabled: true
5 . 考虑我们应用的效率 , 可以配置数据源和线程池 :
package com.wuxicloud.config;
import com.alibaba.druid.pool.DruidDataSource;
import com.alibaba.druid.pool.DruidDataSourceFactory;
import com.alibaba.druid.support.http.StatViewServlet;
import com.alibaba.druid.support.http.WebStatFilter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.env.*;
import javax.sql.DataSource;
import java.util.HashMap;
import java.util.Map;
import java.util.Properties;
@Configuration
public class DruidConfig {
private static final String DB_PREFIX = "spring.datasource.";
@Autowired
private Environment environment;
@Bean
@ConfigurationProperties(prefix = DB_PREFIX)
public DataSource druidDataSource() {
Properties dbProperties = new Properties();
Map map = new HashMap<>();
for (PropertySource propertySource : ((AbstractEnvironment) environment).getPropertySources()) {
getPropertiesFromSource(propertySource, map);
}
dbProperties.putAll(map);
DruidDataSource dds;
try {
dds = (DruidDataSource) DruidDataSourceFactory.createDataSource(dbProperties);
dds.init();
} catch (Exception e) {
throw new RuntimeException("load datasource error, dbProperties is :" + dbProperties, e);
}
return dds;
}
private void getPropertiesFromSource(PropertySource propertySource, Map map) {
if (propertySource instanceof MapPropertySource) {
for (String key : ((MapPropertySource) propertySource).getPropertyNames()) {
if (key.startsWith(DB_PREFIX))
map.put(key.replaceFirst(DB_PREFIX, ""), propertySource.getProperty(key));
else if (key.startsWith(DB_PREFIX))
map.put(key.replaceFirst(DB_PREFIX, ""), propertySource.getProperty(key));
}
}
if (propertySource instanceof CompositePropertySource) {
for (PropertySource s : ((CompositePropertySource) propertySource).getPropertySources()) {
getPropertiesFromSource(s, map);
}
}
}
@Bean
public ServletRegistrationBean druidServlet() {
return new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
}
@Bean
public FilterRegistrationBean filterRegistrationBean() {
FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();
filterRegistrationBean.setFilter(new WebStatFilter());
filterRegistrationBean.addUrlPatterns("/*");
filterRegistrationBean.addInitParameter("exclusions", "*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");
return filterRegistrationBean;
}
}配置线程池 :
package com.wuxicloud.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;
import java.util.concurrent.Executor;
import java.util.concurrent.ThreadPoolExecutor;
@Configuration
@EnableAsync
public class ThreadPoolConfig {
@Bean
public Executor getExecutor() {
ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
executor.setCorePoolSize(5);//线程池维护线程的最少数量
executor.setMaxPoolSize(30);//线程池维护线程的最大数量
executor.setQueueCapacity(8); //缓存队列
executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy()); //对拒绝task的处理策略
executor.setKeepAliveSeconds(60);//允许的空闲时间
executor.initialize();
return executor;
}
}6.用户需要根据用户名进行登录，访问数据库 :
import com.wuxicloud.model.User;
import org.springframework.data.jpa.repository.JpaRepository;
/**
* Created by EalenXie on 2018/7/11 14:23
*/
public interface UserRepository extends JpaRepository {
User findByUsername(String username);
}
7.构建真正用于SpringSecurity登录的安全用户(UserDetails)，我这里使用新建了一个POJO来实现 :
package com.wuxicloud.security;
import com.wuxicloud.model.User;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import java.util.ArrayList;
import java.util.Collection;
public class SecurityUser extends User implements UserDetails {
private static final long serialVersionUID = 1L;
public SecurityUser(User user) {
if (user != null) {
this.setUser_uuid(user.getUser_uuid());
this.setUsername(user.getUsername());
this.setPassword(user.getPassword());
this.setEmail(user.getEmail());
this.setTelephone(user.getTelephone());
this.setRole(user.getRole());
this.setImage(user.getImage());
this.setLast_ip(user.getLast_ip());
this.setLast_time(user.getLast_time());
}
}
@Override
public Collection getAuthorities() {
Collection authorities = new ArrayList<>();
String username = this.getUsername();
if (username != null) {
SimpleGrantedAuthority authority = new SimpleGrantedAuthority(username);
authorities.add(authority);
}
return authorities;
}
@Override
public boolean isAccountNonExpired() {
return true;
}
@Override
public boolean isAccountNonLocked() {
return true;
}
@Override
public boolean isCredentialsNonExpired() {
return true;
}
@Override
public boolean isEnabled() {
return true;
}
}8 . 核心配置，配置SpringSecurity访问策略，包括登录处理，登出处理，资源访问，密码基本加密。
package com.wuxicloud.config;
import com.wuxicloud.dao.UserRepository;
import com.wuxicloud.model.User;
import com.wuxicloud.security.SecurityUser;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
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.Authentication;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.web.authentication.SavedRequestAwareAuthenticationSuccessHandler;
import org.springframework.security.web.authentication.logout.LogoutSuccessHandler;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
/**
* Created by EalenXie on 2018/1/11.
*/
@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
private static final Logger logger = LoggerFactory.getLogger(WebSecurityConfig.class);
@Override
protected void configure(HttpSecurity http) throws Exception { //配置策略
http.csrf().disable();
http.authorizeRequests().
antMatchers("/static/**").permitAll().anyRequest().authenticated().
and().formLogin().loginPage("/login").permitAll().successHandler(loginSuccessHandler()).
and().logout().permitAll().invalidateHttpSession(true).
deleteCookies("JSESSIONID").logoutSuccessHandler(logoutSuccessHandler()).
and().sessionManagement().maximumSessions(10).expiredUrl("/login");
}
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService()).passwordEncoder(passwordEncoder());
auth.eraseCredentials(false);
}
@Bean
public BCryptPasswordEncoder passwordEncoder() { //密码加密
return new BCryptPasswordEncoder(4);
}
@Bean
public LogoutSuccessHandler logoutSuccessHandler() { //登出处理
return new LogoutSuccessHandler() {
@Override
public void onLogoutSuccess(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Authentication authentication) throws IOException, ServletException {
try {
SecurityUser user = (SecurityUser) authentication.getPrincipal();
logger.info("USER : " + user.getUsername() + " LOGOUT SUCCESS ! ");
} catch (Exception e) {
logger.info("LOGOUT EXCEPTION , e : " + e.getMessage());
}
httpServletResponse.sendRedirect("/login");
}
};
}
@Bean
public SavedRequestAwareAuthenticationSuccessHandler loginSuccessHandler() { //登入处理
return new SavedRequestAwareAuthenticationSuccessHandler() {
@Override
public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
User userDetails = (User) authentication.getPrincipal();
logger.info("USER : " + userDetails.getUsername() + " LOGIN SUCCESS ! ");
super.onAuthenticationSuccess(request, response, authentication);
}
};
}
@Bean
public UserDetailsService userDetailsService() { //用户登录实现
return new UserDetailsService() {
@Autowired
private UserRepository userRepository;
@Override
public UserDetails loadUserByUsername(String s) throws UsernameNotFoundException {
User user = userRepository.findByUsername(s);
if (user == null) throw new UsernameNotFoundException("Username " + s + " not found");
return new SecurityUser(user);
}
};
}
}9.至此，已经基本将配置搭建好了，从上面核心可以看出，配置的登录页的url 为/login，可以创建基本的Controller来验证登录了。
package com.wuxicloud.web;
import com.wuxicloud.model.User;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContext;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;
import javax.servlet.http.HttpServletRequest;
/**
* Created by EalenXie on 2018/1/11.
*/
@Controller
public class LoginController {
@RequestMapping(value = "/login", method = RequestMethod.GET)
public String login() {
return "login";
}
@RequestMapping("/")
public String root() {
return "index";
}
public User getUser() { //为了session从获取用户信息,可以配置如下
User user = new User();
SecurityContext ctx = SecurityContextHolder.getContext();
Authentication auth = ctx.getAuthentication();
if (auth.getPrincipal() instanceof UserDetails) user = (User) auth.getPrincipal();
return user;
}
public HttpServletRequest getRequest() {
return ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
}
}11 . SpringBoot基本的启动类 Application.class
package com.wuxicloud;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* Created by EalenXie on 2018/7/11 15:01
*/
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}11.根据Freemark和Controller里面可看出配置的视图为 /templates/index.html和/templates/index.login。所以创建基本的登录页面和登录成功页面。
login.html
