Question

我有一个Spring Rest应用程序，带有有效的API请求。前端方面有些问题。 jQuery get请求不起作用。请帮忙

我尝试了以下代码：

$(document).ready(function() {
    $.ajax({
        url: "http://localhost:8080/posts/"
    }).then(function(data) {
        $('.id').append(data.id);
        $('.content').append(data.content);
    });
});

Spring控制器代码：

@GetMapping("/posts")
public List<Post> getAllPosts() {
    return postRepository.findAll();
}

/ post请求中的数据：
