spring security 实现微信登录
实现微信登录
在本文中,我们将详细描述如何使用Spring Security实现微信登录。我们将一步步地介绍整个过程,包括引入必要的jar包、微信实体信息的定义以及配置Spring Security来支持微信登录。
开发步骤1. 引入jar包首先,我们需要引入必要的jar包。这些jar包与QQ引入的jar包基本一致,包括:
* `spring-security-web`
* `spring-security-config`
* `spring-security-core`
在pom.xml文件中添加以下依赖:
```xml
```
2. 微信实体信息定义微信实体信息的类`WeixinUserInfo`:
```java/
* @author lvhaibao * @description * @date2019/1/400049:46 */
@Datapublic class WeixinUserInfo {
// 微信用户ID private String openid;
// 用户昵称 private String nickname;
// 性别(0:未知,1:男,2:女)
private int sex;
// 国家 private String country;
// 省份 private String province;
// 城市 private String city;
//语言 private String language;
// 头像URL private String headimgurl;
// unionid(只有在unionID模式下有效)
private String unionid;
}
```
3. 配置Spring Security配置Spring Security来支持微信登录。首先,我们需要定义一个`WeixinAuthenticationProvider`类:
```java/
* @author lvhaibao * @description * @date2019/1/400049:46 */
@Componentpublic class WeixinAuthenticationProvider implements AuthenticationProvider {
@Override public Authentication authenticate(Authentication authentication) throws AuthenticationException {
// 从微信服务器获取用户信息 WeixinUserInfo userInfo = getWeixinUserInfo(authentication.getName());
// 创建一个新的`WeixinUserDetails`对象 WeixinUserDetails userDetails = new WeixinUserDetails(userInfo);
// 返回一个新的`Authentication`对象 return new UsernamePasswordAuthenticationToken(userDetails, null, userDetails.getAuthorities());
}
private WeixinUserInfo getWeixinUserInfo(String openid) {
// 从微信服务器获取用户信息 // ...
}
}
```
然后,我们需要定义一个`WeixinUserDetails`类:
```java/
* @author lvhaibao * @description * @date2019/1/400049:46 */
public class WeixinUserDetails implements UserDetails {
private final String openid;
private final String nickname;
private final int sex;
private final String country;
private final String province;
private final String city;
private final String language;
private final String headimgurl;
private final String unionid;
public WeixinUserDetails(WeixinUserInfo userInfo) {
this.openid = userInfo.getOpenid();
this.nickname = userInfo.getNickname();
this.sex = userInfo.getSex();
this.country = userInfo.getCountry();
this.province = userInfo.getProvince();
this.city = userInfo.getCity();
this.language = userInfo.getLanguage();
this.headimgurl = userInfo.getHeadimgurl();
this.unionid = userInfo.getUnionid();
}
@Override public Collection extends GrantedAuthority> getAuthorities() {
// 返回一个集合包含用户的角色信息 // ...
}
@Override public String getPassword() {
return null;
}
@Override public String getUsername() {
return openid;
}
@Override public boolean isAccountNonExpired() {
return true;
}
@Override public boolean isAccountNonLocked() {
return true;
}
@Override public boolean isCredentialsNonExpired() {
return true;
}
@Override public boolean isEnabled() {
return true;
}
}
```
最后,我们需要配置Spring Security来使用我们的`WeixinAuthenticationProvider`:
```java/
* @author lvhaibao * @description * @date2019/1/400049:46 */
@Configurationpublic class WebSecurityConfig implements WebSecurityConfigurer
@Override public void configure(HttpSecurity throws Exception {
// 配置HTTP安全 // ...
}
@Override public AuthenticationManager authenticationManagerBean() throws Exception {
// 返回一个新的`AuthenticationManager`对象 return new WeixinAuthenticationProvider();
}
}
```
