登录模块

实体类：hr，要继承UserDetails，并实现里面的一些方法

package org.lizhen.vhrdemo.model;
import com.fasterxml.jackson.annotation.JsonIgnore;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;

import java.util.Objects;
public class Hr implements UserDetails {
    private Integer id;
    private String name;
    private String phone;
    private String telephone;
    private String address;
    private Boolean enabled;
    private String username;
    private String password;
    private String userface;
    private String remark;
    private List<Role> roles;
    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;
        Hr hr = (Hr) o;
        return Objects.equals(username, hr.username);
    }
    @Override
    public int hashCode() {
        return Objects.hash(username);
    }
    public List<Role> getRoles() {
        return roles;
    }
    public void setRoles(List<Role> roles) {
        this.roles = roles;
    }
    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name == null ? null : name.trim();
    }
    public String getPhone() {
        return phone;
    }
    public void setPhone(String phone) {
        this.phone = phone == null ? null : phone.trim();
    }
    public String getTelephone() {
        return telephone;
    }
    public void setTelephone(String telephone) {
        this.telephone = telephone == null ? null : telephone.trim();
    }
    public String getAddress() {
        return address;
    }
    public void setAddress(String address) {
        this.address = address == null ? null : address.trim();
    }
    public void setEnabled(Boolean enabled) {
        this.enabled = enabled;
    }
    public String getUsername() {
        return username;
    }
    @Override
    public boolean isAccountNonExpired() {
        return true;
    }
    @Override
    public boolean isAccountNonLocked() {
        return true;
    }
    @Override
    public boolean isCredentialsNonExpired() {
        return true;
    }
    @Override
    public boolean isEnabled() {
        return enabled;
    }
    public void setUsername(String username) {
        this.username = username == null ? null : username.trim();
    }
    @Override
    @JsonIgnore
    public Collection<? extends GrantedAuthority> getAuthorities() {
        List<SimpleGrantedAuthority> authorities = new ArrayList<>(roles.size());
        for (Role role : roles) {
            authorities.add(new SimpleGrantedAuthority(role.getName()));
        }
        return authorities;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password == null ? null : password.trim();
    }
    public String getUserface() {
        return userface;
    }
    public void setUserface(String userface) {
        this.userface = userface == null ? null : userface.trim();
    }
    public String getRemark() {
        return remark;
    }
    public void setRemark(String remark) {
        this.remark = remark == null ? null : remark.trim();
    }
}

HrService：需要继承UserDetailsService

@Service
public class HrService implements UserDetailsService {

    @Autowired
    HrMapper hrMapper;
    @Autowired
    HrRoleMapper hrRoleMapper;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        Hr hr = hrMapper.loadUserByUsername(username);
        if (hr == null) {
            throw new UsernameNotFoundException("用户名不存在!");
        }
        hr.setRoles(hrMapper.getHrRolesById(hr.getId()));
        return hr;
    }
}

loadUserByUsername()内部调用userMapper的loadUserByUsername()，这是自己写的。是为了从数据库里查询相关信息。查出来后，交给springSecurity去对比密码就好了。
