5.3 JWT工具类
在ihrm_common工程中创建JwtUtil工具类
代码语言：javascript复制@ConfigurationProperties("jwt.config")
public class JwtUtil {
private String key;
private long ttl;
public String getKey() {
return key;
}
public void setKey(String key) {
this.key = key;
}
public long getTtl() {
return ttl;
}
public void setTtl(long ttl) {
this.ttl = ttl;
}
/**
* 签发 token
*/
public String createJWT(String id, String subject,Map<String,Object> map){
long now=System.currentTimeMillis();
long exp=now ttl;
JwtBuilder jwtBuilder = Jwts.builder().setId(id)
.setSubject(subject).setIssuedAt(new Date())
.signWith(SignatureAlgorithm.HS256, key);
for(Map.Entry<String,Object> entry:map.entrySet()) {
jwtBuilder.claim(entry.getKey(),entry.getValue());
}
if(ttl>0){
jwtBuilder.setExpiration( new Date(exp));
}
String token = jwtBuilder.compact();
return token;
}
/**
* 解析JWT
* @param token
* @return
*/
public Claims parseJWT(String token){
Claims claims = null;
try {
claims = Jwts.parser()
.setSigningKey(key)
.parseClaimsJws(token).getBody();
}catch (Exception e){
}
return claims;
}
}（3） 修改ihrm_common工程的application.yml, 添加配置
代码语言：javascript复制jwt:
config:
key: saas-ihrm
ttl: 3600005.4 登录成功签发token
（1）配置JwtUtil。修改ihrm_system工程的启动类
代码语言：javascript复制@Bean
public JwtUtil jwtUtil(){
return new util.JwtUtil();
}（2）添加登录方法
代码语言：javascript复制 /**
* 用户登录
* 1.通过service根据mobile查询用户
* 2.比较password
* 3.生成jwt信息
*
*/
@RequestMapping(value="/login",method = RequestMethod.POST)
public Result login(@RequestBody Map<String,String> loginMap) {
String mobile = loginMap.get("mobile");
String password = loginMap.get("password");
User user = userService.findByMobile(mobile);
//登录失败
if(user == null || !user.getPassword().equals(password)) {
return new Result(ResultCode.MOBILEORPASSWORDERROR);
}else {
//登录成功
Map<String,Object> map = new HashMap<>();
map.put("companyId",user.getCompanyId());
map.put("companyName",user.getCompanyName());
String token = jwtUtils.createJwt(user.getId(), user.getUsername(), map);
return new Result(ResultCode.SUCCESS,token);
}
}（3）测试运行结果
使用postman验证登录返回：
代码语言：javascript复制{"success":true,"code":10000,"message":"操作成
功！","data":"eyJhbGciOiJIUzI1NiJ9.eyJqdGkiOiIxMDYyNjYxODkxNjE4Mzc3NzI4Iiwic3ViIjoiemhhb
