使用Spring启动,MySQL,JPA和RESTFUL CRUD API。
我要做的是将参数传递给Controller,以便参数进入表格。但是null值进入表中我无法确定哪个部分是问题。只有我能确定控制器没有收到适当的值。
在下面,我发布了Entity类(Status.java),Controller(GuideController.java)和html表单(guide.html)。
Status.java
@Entity
@Table(name="tbl_status")
public class Status {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private Integer id;
private String xml_to_json;
public String getXml_to_json() {
return xml_to_json;
}
public void setXml_to_json(String xml_to_json) {
this.xml_to_json = xml_to_json;
}
GuideController.java
@Autowired
private StatusRepository statusRepository;
@GetMapping(path="/insert") // Map ONLY GET Requests
public @ResponseBody String addNewStatus (@RequestParam String xml_to_json
, @RequestParam String json_to_xml) {
// @ResponseBody means the returned String is the response, not a view name
// @RequestParam means it is a parameter from the GET or POST request
Status s = new Status();
s.setXml_to_json(xml_to_json);
//s.setJson_to_xml(json_to_xml);
statusRepository.save(s);
return "Saved";
}
@GetMapping(path="/all")
public @ResponseBody Iterable<Status> getAllUsers() {
// This returns a JSON or XML with the users
return statusRepository.findAll();
}
guide.html
var xml2json = function(_data){
$.ajax({
type: "POST",
url: url + "xml2json",
data: _data,
contentType : "application/xml",
cache: false,
success : function(data) {
$("#output-xml-to-json").html(JSON.stringify(data,null,4));
$.ajax({
type:"POST",
url: url + "insert",
data: {xml_to_json:"success"},
contentType: "text"
})
},
error : function(){
$("#output-xml-to-json").html("xml2json error");
$.ajax({
type:"POST",
url: url + "insert",
data: {xml_to_json:"error"},
contentType: "text"
})
}
});
}
答案 0 :(得分:0)
请求映射是GET:
@GetMapping(path="/insert") // Map ONLY GET Requests
public @ResponseBody String addNewStatus (@RequestParam String xml_to_json
, @RequestParam String json_to_xml) {...}
AJAX请求是带有json数据的POST。应该获取AJAX请求,并且必须在查询字符串中传递xml_to_json
。
