将数据从 POST Curl 插入到 JAVA Spring - Insert Data from POST Curl to JAVA Spring

我有这个json POST url'http：//localhost：8080/demo/test' from PHP

'{"postby_id":"1","title":"ftkjhg","is_private":"0","status":"1","post_type_id":"1","type":"2","p_id":"1","ve_id":"3","link":"1111111"}'

我的网络控制器

    @RequestMapping(value = "/test", method = RequestMethod.POST)
    @ResponseBody
    void creMysqlCall() throws Exception {

        creativityService.creMysqlCall();
    }

服务文件

public void creMysqlCall() throws Exception {
        creativityDao.creMysqlCall();
    }

我的DAO文件

public void creMysqlCall() throws Exception {
        SimpleJdbcInsert simpleJdbcInsert = new SimpleJdbcInsert(masterJdbcTemplate).withTableName("posts")
                .usingColumns("postby_id","title","is_private","post_type_id","status","wall_type","p_id","ve_id","link");
        Map<String, Object> creInsertMap = Maps.newHashMap();
        creInsertMap.put("postby_id", "");
        creInsertMap.put("title", "");
        creInsertMap.put("is_private", "");
        creInsertMap.put("post_type_id", "");
        creInsertMap.put("status", "");
        creInsertMap.put("wall_type", "");
        creInsertMap.put("p_id", "");
        creInsertMap.put("ve_id", "");
        creInsertMap.put("link", "");

我如何将数据从 URL 发布到这个 DAO 我是 Java 新手提前感谢

更新

收到此错误

HTTP 错误 405访问/后端/测试时出现问题。原因：不支持请求方法"GET"

使用 getter 和 setter 的新类文件

public class MysqlCall {

    public Object is_private;
    public Object postby_id;
    public Object title;
    public Object getPostby_id() {
        return postby_id;
    }
    public void setPostby_id(Object postby_id) {
        this.postby_id = postby_id;
    }
    public Object getTitle() {
        return title;
    }
    public void setTitle(String title) {
        this.title = title;
    }
    public Object getIs_private() {
        return is_private;
    }
    public void setIs_private(String is_private) {
        this.is_private = is_private;
    }
    public Object getStatus() {
        return status;
    }
    public void setStatus(String status) {
        this.status = status;
    }
    public Object getPost_type_id() {
        return post_type_id;
    }
    public void setPost_type_id(String post_type_id) {
        this.post_type_id = post_type_id;
    }
    public Object getWall_type() {
        return wall_type;
    }
    public void setWall_type(String wall_type) {
        this.wall_type = wall_type;
    }
    public Object getPostto_id() {
        return postto_id;
    }
    public void setPostto_id(String postto_id) {
        this.postto_id = postto_id;
    }
    public Object getVertical_id() {
        return vertical_id;
    }
    public void setVertical_id(String vertical_id) {
        this.vertical_id = vertical_id;
    }
    public Object getLink() {
        return link;
    }
    public void setLink(String link) {
        this.link = link;
    }
    public Object status;
    public Object post_type_id;
    public Object wall_type;
    public Object postto_id;
    public Object vertical_id;
    public Object link;

新道

public void creMysqlCall(MysqlCall call) throws Exception {
        SimpleJdbcInsert simpleJdbcInsert = new SimpleJdbcInsert(masterJdbcTemplate).withTableName("posts")
                .usingColumns("postby_id","title","is_private","post_type_id","status","wall_type","postto_id","vertical_id","link");
        Map<String, Object> creInsertMap = Maps.newHashMap();
        creInsertMap.put("postby_id", call.postby_id);
        creInsertMap.put("title", call.title);
        creInsertMap.put("is_private", call.is_private);
        creInsertMap.put("post_type_id", call.post_type_id);
        creInsertMap.put("status", call.status);
        creInsertMap.put("wall_type", call.wall_type);
        creInsertMap.put("postto_id", call.postto_id);
        creInsertMap.put("vertical_id", call.vertical_id);
        creInsertMap.put("link", call.link);

服务文件

public void creMysqlCall(MysqlCall call) throws Exception {
    creativityDao.creMysqlCall(call);
}

控制器

用于测试服务调用的 API@RequestMapping（值 = "/test"，方法 = RequestMethod.POST，消耗 = MediaType.APPLICATION_JSON_VALUE）

void creMysqlCall（@RequestBody（required = true） MysqlCall call ）抛出异常 {

creativityService.creMysqlCall(call);

}

您需要使用 getter 和 setter 从 JSON 创建一个值对象类。

然后您的控制器将看起来像

@RequestMapping(value = "/test", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE)
@ResponseBody
void creMysqlCall(@RequestBody(required = true) MysqlCall call) throws Exception {
   creativityService.creMysqlCall(call);
}

确保你的班级路径中有杰克逊，所以在你的pom

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.6.0</version>
</dependency>

这

更像是一个Spring MVC和Jackson的问题。你必须创建一个类，如下所示：

public class MysqlCall {
   private String postby_id;
   /* the rest of the fields in JSON */
   /* getters and setters */
}

然后使用 @RequestBody 注释对其进行映射：

@RequestMapping(value = "/test", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE)
public @ResponseBody Object creMysqlCall(@RequestBody(required = true) MysqlCall call) throws Exception {
    //creativityService.creMysqlCall(call);
    return call;
}

在 DAO 中，您只需将对象参数与 sql 映射链接即可。
