小编use*_*407的帖子

我试图在spring-boot应用程序中使用spring-data-redis来处理redis.我创建JedisConnectionFactory如下:

RedisStandaloneConfiguration configuration = new RedisStandaloneConfiguration();
configuration.setHostName("localhost");
configuration.setPort(6379);
JedisConnectionFactory connectionFactory = new JedisConnectionFactory(configuration);

它抛出了异常:

我的build.gradle:

dependencies {
    compile('org.springframework.data:spring-data-redis:2.0.2.RELEASE')
    compile('redis.clients:jedis:2.9.0')
    compile('org.json:json:20160810')
    compile('org.springframework.boot:spring-boot-starter:1.4.2.RELEASE')
    compile("org.springframework:spring-web")
    compile('org.slf4j:slf4j-api:+')
}

是因为spring-boot和spring-data-redis的不兼容的依赖版本？我怎么知道要使用哪个版本？

特别是在readUnshared()方法的背景下,ObjectInputStream"反向引用"是什么意思？

我在这里遇到了这个词

如果调用readUnshared反序列化反向引用(先前已写入流的对象的流表示),则抛出ObjectStreamException.

参考:https://docs.oracle.com/javase/7/docs/api/java/io/ObjectInputStream.html#readUnshared()

我有这样的事情：

public interface SomeInterface {
    public String someMethod(String someArg1, String someArg2);
}

public class SomeInterfaceImpl {

    @Override
    public String someMethod(String someArg1, String someArg2) {
        String response;

        // a REST API call which fetches response (need to mock this)

        return response;
    }
}

public class SomeClass {

    public int execute() {

        int returnValue;

        // some code

        SomeInterface someInterface = new SomeInterfaceImpl();
        String response = someInterface.someMethod("some1", "some2");

        // some code

        return returnValue;
    }
}

我想execute()在SomeClass使用 JUnit 时测试该方法。由于someMethod(String …

我试图实现与此相同的事情:如何使用Spring RestTemplate表示为JSON的查询参数？,将JSON字符串作为URL参数发送restTemplate.exchange().

接受的答案提到将JSON对象作为请求参数发送通常不是一个好主意,因为您可能会遇到JSON中的大括号问题.这正是我尝试对API进行GET调用时发生的事情.由于这是来自另一个系统的API,我不能要求他们更改格式,并且必须调用GET端点,将JSON作为参数传递.我怎样才能实现这一目标restTemplate.exchange()？

注意:提到的相关问题没有指导如何克服这个问题,我没有足够的声誉来评论它,以询问作者的答案.
