Java函数的生态系统和社区支持情况如何？社区支持维度

@Function("handle-request")
public String handleRequest(@CloudEvent CloudEvent cloudEvent,
                            @RequestPayload String requestBody) {
  String sql = "SELECT * FROM users WHERE name = ?";
  JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource());
  List<User> users = jdbcTemplate.query(sql, (ps) -> ps.setString(1, requestBody), (rs, rowNum) ->
   new User(rs.getLong("id"), rs.getString("name")));
  return String.valueOf(users.size());
}

// 数据源配置
@Bean
public DataSource dataSource() {
    try {
        HikariDataSource dataSource = new HikariDataSource();
        dataSource.setDriverClassName("com.mysql.cj.jdbc.Driver");
        dataSource.setJdbcUrl("jdbc:mysql://localhost:3306/demo");
        dataSource.setUsername("root");
        dataSource.setPassword("password");
        return dataSource;
    } catch (Exception e) {
        throw new RuntimeException(e);
    }

// 事件类型配置
@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication app = new SpringApplication(Application.class);
        //CloudEventBuilder和ObjectMapper使Spring框架能够解析Message和Payload属性
        app.addInitializers(new CloudEventCloudFunctionInitializer());
        app.run(args);
    }
}

@FunctionName("handle-blob-event")
