我的项目是创建一个输入页面,用于在其中输入一些文本并将其发送到 mysql (phpmyadmin) 。我正在使用 spring-boot 2.1.4 和 Angular 7。
预先感谢您的调查!爱
我专注于 GraphController.java 并尝试多种替代方案@CrossOrigin
。我试图在全球范围内调用它,但什么也没有......
这是我的来源https://spring.io/blog/2015/06/08/cors-support-in-spring-framework我也什么也没尝试
我的实体(Graph.java)
@Entity(name = "graphiques")
@Table(name ="graphiques")
@Data
@NoArgsConstructor
@AllArgsConstructor
public class Graph {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name ="id")
private Long id;
@Column(name ="xml")
private String xml;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getXml() {
return xml;
}
public void setXml(String xml) {
this.xml = xml;
}
}
我的 GraphController.java
@RestController
@CrossOrigin
@RequestMapping("/insert")
public class GraphController {
@Autowired
GraphRepository graphRepository;
@GetMapping
@ResponseBody
public String addGraph(@RequestParam String xml) {
Graph graph = new Graph();
graph.setXml(xml);
graphRepository.save(graph);
String ret = "Graph has been added";
return ret;
}
我在 Angular 中的 xml-insert-form.component.ts
insertForm: FormGroup;
xml: string;
submitted = false;
graph: Graph;
initForm() {
this.insertForm = this.formBuilder.group({
xml: ['', Validators.required]
});
}
onSubmit() {
const xml = this.insertForm.get('xml').value;
const newGraph = new Graph(xml);
this.graphService.createNewGraph(newGraph).subscribe(
graph => {
console.log('onSubmit OK');
},
error => console.log('Erreur lors de l\'ajout du nouveau graph')
);
this.submitted = true;
}
在 mysql 中,我有 1 个名为“sogetiauditback”的数据库和一个名为“graphiques”的表,其中包含“id”和“xml”列。 (xml 将是输入文本的纯文本)
预期结果:没有 403 错误,输入中的数据发送到 mysql
错误消息(谷歌浏览器:
- polyfills.js:3251 OPTIONS http://localhost:8282/insert 403
