大家好，欢迎来到IT知识分享网。
boke例子：用户登录
1.首先创建user表，authority表（角色），user_authority,表（用户角色表）
Authority实体类，需要继承：GrantedAuthority类，
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import org.springframework.security.core.GrantedAuthority;
/**
* 权限
* @author
*
*/
@Entity
public class Authority implements GrantedAuthority {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Long id;
@Column(nullable=false, length=20)
private String name;
@Override
public String getAuthority() {
// TODO Auto-generated method stub
return name;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public void setName(String name) {
this.name = name;
}
}
User类.需要继承security的UserDetails类：
并复写：isAccountNonExpired，isAccountNonLocked，isCredentialsNonExpired， isEnabled返回true值
同事复写：
@Override
public Collection<? extends GrantedAuthority> getAuthorities() {
//需将 List<Authority> 转成 List<SimpleGrantedAuthority>，否则前端拿不到角色列表名称
List<SimpleGrantedAuthority> simpleGrantedAuthorities = new ArrayList<>();
for(GrantedAuthority authority: this.authorities)
{
simpleGrantedAuthorities.add(new SimpleGrantedAuthority(authority.getAuthority()));
}
return simpleGrantedAuthorities;
}
如下：
import java.io.Serializable;
import java.util.ArrayList;
import java.util.Collection;
import java.util.List;
import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.JoinTable;
import javax.persistence.ManyToMany;
import javax.validation.constraints.Size;
import org.hibernate.validator.constraints.Email;
import org.hibernate.validator.constraints.NotEmpty;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
@Entity
public class User implements UserDetails,Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
//private AtomicLong atomicLong = new AtomicLong();
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Long id;
@NotEmpty(message="姓名不能为空")
@Size(min=2, max=20)
@Column(nullable=false, length=20)
private String name;
@NotEmpty(message="邮箱不能为空")
@Size(max=50)
@Email(message="邮箱格式不正确")
@Column(nullable=false, length=50, unique=true)
private String email;
@NotEmpty(message="账号不能为空")
@Size(min=3, max=20)
@Column(nullable=false, length=20, unique=true)
private String username;
@NotEmpty(message="密码不能为空")
@Size(min=3, max=20)
@Column(nullable=false, length=20)
private String password;
@Column(length=200)
private String avatar;
//权限多对多
@ManyToMany(cascade = CascadeType.DETACH, fetch = FetchType.EAGER)
@JoinTable(name = "user_authority", joinColumns = @JoinColumn(name = "user_id", referencedColumnName = "id"),
inverseJoinColumns = @JoinColumn(name = "authority_id", referencedColumnName = "id"))
private List<Authority> authorities;
public User() {
}
public User(Long id, String name, String email, String username, String password) {
this.id = id;
this.name = name;
this.email = email;
this.username = username;
this.password = password;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getAvatar() {
return avatar;
}
public void setAvatar(String avatar) {
this.avatar = avatar;
}
@Override
public String toString() {
return "User [id=" + id + ", name=" + name + ", email=" + email + ", username=" + username + "]";
}
@Override
public Collection<? extends GrantedAuthority> getAuthorities() {
//需将 List<Authority> 转成 List<SimpleGrantedAuthority>，否则前端拿不到角色列表名称
List<SimpleGrantedAuthority> simpleGrantedAuthorities = new ArrayList<>();
for(GrantedAuthority authority: this.authorities)
{
simpleGrantedAuthorities.add(new SimpleGrantedAuthority(authority.getAuthority()));
}
return simpleGrantedAuthorities;
}
public void setAuthorities(List<Authority> authorities) {
this.authorities = authorities;
}
@Override
public boolean isAccountNonExpired() {
// TODO Auto-generated method stub
return true;
}
@Override
public boolean isAccountNonLocked() {
// TODO Auto-generated method stub
return true;
}
@Override
public boolean isCredentialsNonExpired() {
// TODO Auto-generated method stub
return true;
}
@Override
public boolean isEnabled() {
// TODO Auto-generated method stub
return true;
}
}
同事创建user的userservice及userserviceImpl实现类，serviceImple继承userService和security的UserDetailsService
UserService:
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import com.muyang.boke2.entity.User;
/**
* 用户服务接口
* @author feeyo
*
*/
public interface UserService {
/**
* 保持用户
* @param user
* @return
*/
User saveOrUpdateUser(User user);
/**
* 注册用户
* @param user
* @return
*/
User registerUser(User user);
/**
* 删除用户
* @param id
*/
void removeUser(Long id);
/**
* 根据id查找用户
* @param id
* @return
*/
User findById(Long id);
/**
* 根据用户的姓名分页查找用户
* @param name
* @param pageable
* @return
*/
Page<User> listUsersByName(String name, Pageable pageable);
/**
* 按分页查找数据
* @param pageable
* @return
*/
Page<User> findAll(Pageable pageable);
}
UserServiceImpl:
继承security的UserDetailsService ，复写loadUserByUsername方法
/**
* 用户服务接口实现
* @author feeyo
*
*/
@Service
public class UserServiceImpl implements UserService, UserDetailsService {
@Autowired
UserRepository userRepository;
@Transactional
@Override
public User saveOrUpdateUser(User user) {
// TODO Auto-generated method stub
return userRepository.save(user);
}
@Transactional
@Override
public User registerUser(User user) {
// TODO Auto-generated method stub
return userRepository.save(user);
}
@Transactional
@Override
public void removeUser(Long id) {
// TODO Auto-generated method stub
userRepository.delete(id);
}
@Override
public User findById(Long id) {
// TODO Auto-generated method stub
return userRepository.findOne(id);
}
@Override
public Page<User> listUsersByName(String name, Pageable pageable) {
// TODO Auto-generated method stub
name = "%" + name + "%";
Page<User> users = userRepository.findByNameLike(name, pageable);
return users;
}
@Override
public Page<User> findAll(Pageable pageable) {
// TODO Auto-generated method stub
Page<User> users = userRepository.findAll(pageable);
return users;
}
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
// TODO Auto-generated method stub
return userRepository.findByUsername(username);
}
}
SecurityConfig网站全局配置/登录配置
@EnableWebSecurity
//启用全局post安全方法设置
@EnableGlobalMethodSecurity(prePostEnabled=true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
private static final String key = "muyang.my";
@Autowired
private UserDetailsService userDetailsService;
/**
* 加密方法
* @return
*/
@Bean
public PasswordEncoder passwordEncoder()
{
return new BCryptPasswordEncoder();
}
@Bean
public AuthenticationProvider authenticationProvider() {
//从数据库获取信息
DaoAuthenticationProvider authenticationProvider = new DaoAuthenticationProvider();
authenticationProvider.setUserDetailsService(userDetailsService);
//密码加密方式
authenticationProvider.setPasswordEncoder(passwordEncoder());
return authenticationProvider;
}
@Override
protected void configure(HttpSecurity http) throws Exception {
// TODO Auto-generated method stub
//super.configure(http);
//关闭csrf验证:跨站攻击
//http.csrf().disable();
//权限设置
http.authorizeRequests() //定义那些url需要保护，哪些不需要保护
.antMatchers("/static/**").permitAll() //都可以访问
.antMatchers("/user/**").hasRole("ADMIN") //需要登陆才能访问
.and()
.headers().frameOptions().disable() //解决js跨站把x-frame-options disable即可
.and()
.formLogin() //基于FORM表单登陆验证
.loginPage("/login").failureUrl("/login-error") //自定义登陆界面//自定义登陆错误页面
.and().rememberMe().key(key) //记住我
.and().exceptionHandling().accessDeniedPage("/403"); // 处理异常，拒绝访问就重定向到 403 页面
}
/**
* 认证信息管理
* @param auth
* @throws Exception
*/
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
// TODO Auto-generated method stub
//super.configure(auth);
//auth.inMemoryAuthentication().withUser("admin").password("123456").roles("ADMIN");
auth.userDetailsService(userDetailsService);
auth.authenticationProvider(authenticationProvider());
}
/**
* 自动加载security-taglibs
* @return
*/
@Bean
@ConditionalOnMissingBean(ClassPathTldsLoader.class)
public ClassPathTldsLoader classPathTldsLoader(){
return new ClassPathTldsLoader();
}
}
