RESTAPI有很多异常

我现在正在开发RESTAPI，但我发现这非常困难。控制台向我展示了很多异常，我不知道该怎么解决。 所以，请，这是我的代码：

package API;
import javax.ws.rs.DefaultValue;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.QueryParam;
import javax.ws.rs.core.MediaType;
import org.neo4j.graphdb.Node;
import function.query.weceipt.GraphManagement;

@Path("/API")
public class MyService {    

@POST
@Path("/node")
@Produces({ MediaType.APPLICATION_JSON })
public Node createNode(@DefaultValue("default_id") @QueryParam("ID") String id) {
    GraphManagement gm = new GraphManagement();
    Node node = gm.createClientNode(id);

    return node;
}

@GET 
@Path("/node/{ID}")
@Produces({ MediaType.APPLICATION_JSON })
public Node getNode(@PathParam("ID") String id) {
    GraphManagement gm = new GraphManagement();
    Node node = gm.getClientNode(id);

    return node;
}

@Path("/test")
@GET
@Produces(MediaType.TEXT_PLAIN)
public void afficher() {
    System.out.println("test");
}
}

这是控制台向我展示的一个示例：

有人能帮我解决这些异常吗

我不确定这一点，但我认为，在我的代码中，我应该在代码中的neo4j对象节点和JSON之间进行解析，但如果这真的是我问题的解决方案，我也不知道如何进行解析

谢谢。

NoClassDefFound表示您缺少对类路径的运行时依赖性。我不知道neo4j的情况，但似乎缺少了一些东西。您应该检查是否具有所有必需的依赖项如何管理依赖项？你用Maven吗？我根本没用Maven！我不知道这是否是我问题的根源，但我不这么认为。是否可以在现有项目中包含maven？还是我必须从一开始就用maven架构开始一个新项目？最后一个问题，你真的确定maven可以解决这些问题吗？因为我不知道如何很好地使用它，我正在犹豫使用它。。。感谢you@fujitsu4您也可以只导入丢失的jar，而不使用maven。对于你的下一个项目，我建议你了解maven。
