将数据从卷曲后插入到Java spring

Question

我有一个来自PHP的json POST URL“http：//localhost:8080/demo/test”

'{"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webController

    @RequestMapping(value = "/test", method = RequestMethod.POST)

    @ResponseBody
    void creMysqlCall() throws Exception {


        creativityService.creMysqlCall();

    }

服务文件

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

myDAO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", "");

我怎样才能从URL到这个道上发布数据，我对Java是新的，提前感谢

更新

我发现了这个错误

HTTP错误405访问/backend/test时出现问题。原因：不支持请求方法“Get”

使用getter和setter新建类文件

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;

新刀

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@RequestMapping的API（值=“/test”,方法=RequestMethod.Post,消耗=MediaType.Application_JSON_Value)

void creMysqlCall(@requestbody(required=true）MysqlCall调用）引发异常{

creativityService.creMysqlCall(call);

}

Answer 1

您需要使用getter和setter从JSON创建一个Value Object类。

那么您的控制器看起来就像

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

确保在类路径中有jackson，因此在pom中

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