我有一个如下的 POJO,它包含其他 POJO 的列表:
public class Commit {
private long revision;
private Date date;
private String author;
private String comment;
private String akuiteo;
private List<ChangedPath> changedPathList = new ArrayList<ChangedPath>();
//Getters, Setters and Constructor following
}

我的控制器需要 3 个参数,其中一个是数组或提交列表:
@RequestMapping(value="/selectedCommits",method=RequestMethod.POST)
@ResponseBody
public List<Commit> getAllDependentCommits(@RequestParam("branch")String branch,
@RequestParam("tag")String tagName,@RequestParam(value="commits[]") Commit[] commits) throws IOException{
List<String> changedPaths=new ArrayList<String>();
List<Commit> dependentCommits=UserService.listAllCommits(branch, tagName, commits);
//UserService.createPatchFromSelectedCommits(branch, tagName, revisions);
return dependentCommits;
}

我也试过:List<Commit> commits
而不是Commit[ ] commits
我使用 AJAX 从 jQuery 脚本调用控制器:
$("#buttonCommit").click(function(e){
console.log(branch);
console.log(tag);
console.log(selectedCommits);
$.ajax({
url:'selectedCommits?branch='+branch+'&tag='+tag,
method: 'POST',
dataType: 'application/json',
contentType: 'application/json; charset=utf-8',
data:{
commits:selectedCommits,
},
success:function(data){
alert('wow smth really happened, here is the response : '+data[1]);
window.selectedCommits=selectedCommits;
window.dependentCommits=data.dependentCommits;
console.log(data.dependentCommits);
}
})
});

我也试过: commits:JSON.stringify(selectedCommits)
每次我收到错误:
org.springframework.web.bind.MissingServletRequestParameterException:
Required Commit[] parameter 'commits[]' is not present

我还测试了传递代表修订的 Long 数组并且它起作用了,我可以管理将它用于我的服务,但是拥有一个对象数组会更好。我究竟做错了什么?
你应该使用
@RequestBody List<Commit> commits

在您的控制器中而不是
@RequestParam(value="commits[]") Commit[] commits
