登陆接口

Controller

@PostMapping("/login")
public Result<Map<String, Object>> login(@RequestBody User user) {
    System.out.println(user);
    HashMap<String, Object> map = userService.login(user);
    if (map == null) {
        return Result.fail(map, "用户名或者密码不对");
    }
    return Result.success(map, "登陆成功");
}

Service

@Override
public HashMap<String, Object> login(User user) {
    LambdaQueryWrapper<User> queryWrapper = new LambdaQueryWrapper<>();
    queryWrapper.eq(User::getUsername, user.getUsername());
    // queryWrapper.eq(User::getPassword, user.getPassword());
    User loginUser = userMapper.selectOne(queryWrapper);
    // 如果没有用户
    if(loginUser == null) {
        return null;
    }
    if(!passwordEncoder.matches(user.getPassword(), loginUser.getPassword())) {
        return null;
    }
    // 生成token
    String key = "user:" + UUID.randomUUID();
    // 存入redis
    loginUser.setPassword(null);
    redisTemplate.opsForValue().set(key, loginUser, 30, TimeUnit.MINUTES);
    // 返回数据
    HashMap<String, Object> map = new HashMap<>();
    map.put("token", key);
    return map;
}

Redis配置

@Configuration
public class MyRedisConfig {
    @Resource
    private RedisConnectionFactory factory;

    @Bean
    public RedisTemplate redisTemplate() {
        RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(factory);

        // 为了更好的查看redis key内容，设置一个序列化器
        redisTemplate.setKeySerializer(new StringRedisSerializer());

        // 为了更好的查看redis value内容，设置一个序列化器
        Jackson2JsonRedisSerializer<Object> serializer = new Jackson2JsonRedisSerializer<>(Object.class);
        redisTemplate.setValueSerializer(serializer);

        ObjectMapper om = new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.setDateFormat(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"));
        om.setTimeZone(TimeZone.getDefault());
        om.configure(MapperFeature.USE_ANNOTATIONS, false);
        om.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
        om.configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false);
        om.activateDefaultTyping(LaissezFaireSubTypeValidator.instance ,ObjectMapper.DefaultTyping.NON_FINAL, JsonTypeInfo.As.PROPERTY);
        om.setSerializationInclusion(JsonInclude.Include.NON_NULL);
        serializer.setObjectMapper(om);
        return redisTemplate;
    }
}
