Spring 4 gs rest服务给出不可接受的406错误

我正在尝试运行示例gs rest服务complete（）并获取：

我没有对代码做任何修改

下面是Greeting.java文件

package hello;

public class Greeting {

private final long id;
private final String content;

public Greeting(long id, String content) {
    this.id = id;
    this.content = content;
}

public long getId() {
    return id;
}

public String getContent() {
    return content;
}
}

控制器类：

package hello;

import java.util.concurrent.atomic.AtomicLong;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class GreetingController {

private static final String template = "Hello, %s!";
private final AtomicLong counter = new AtomicLong();

@RequestMapping(value="/greeting")
public Greeting greeting(@RequestParam(value="name", defaultValue="World") String name) {
    return new Greeting(counter.incrementAndGet(),
                        String.format(template, name));
}
}

我使用应用程序类通过spring boot启动：

package hello;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {

public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
}
}

下面是pom.xml文件：

我使用Spring工具套件并直接从服务器导入项目。我使用SpringBoot运行该项目

有什么我忘记的具体配置吗

---

通过在pom.xml中添加2个依赖项，我最终实现了这个示例：

    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-core</artifactId>
    </dependency>
    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-annotations</artifactId>
    </dependency>

com.fasterxml.jackson.core
杰克逊核心
com.fasterxml.jackson.core
杰克逊注释

这是一种奇怪的行为，因为这些依赖项包含在spring boot中：

        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-annotations</artifactId>
            <version>${jackson.version}</version>
        </dependency>
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-core</artifactId>
            <version>${jackson.version}</version>
        </dependency>
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
            <version>${jackson.version}</version>
        </dependency>

com.fasterxml.jackson.core
杰克逊注释
${jackson.version}
com.fasterxml.jackson.core
杰克逊核心
${jackson.version}
com.fasterxml.jackson.core
杰克逊数据绑定
${jackson.version}

它对jackson databind有效，但对另外两个无效

如果有人能解释这一点，请让我知道。

在不做任何调查的情况下，我会尝试的第一件事是将您请求的

Accept

头设置为

application/json

我尝试添加此项，但结果相同，我得到的状态是406。我只是用新的STS安装环境，并直接从spring示例导入，可能我错过了一些前提条件您应该添加解决方案，作为问题的答案。面对同一问题的人更容易找到答案。
