Spring rest服务使用@RestController将多个实体类作为xml响应返回

@XmlRootElement
public class Entity1 {
    // 实体类的属性和方法
}

@XmlRootElement
public class Entity2 {
    // 实体类的属性和方法
}

@RestController
public class MyController {
    @GetMapping("/entities")
    public List<Object> getEntities() {
        List<Object> entities = new ArrayList<>();
        // 从数据库或其他数据源获取实体类数据，并添加到entities列表中
        entities.add(new Entity1());
        entities.add(new Entity2());
        return entities;
    }
}
