我正在尝试使用模拟 2.0.2 和 mockito 2.0。以前我用powermock来模拟一些局部变量：我在测试类上用过

 @RunWith(PowerMockRunner.class)
 @PrepareForTest({MyClass.class})
 whenNew(MyClass.class).withAnyArguments().thenReturn(myClassMock);

一切都很好，带有电源模拟1.6。当我试图转移到Powermock 2.X我不能再找到whenNew（）在PowerMock方法。这在新的 Powermock 中有何变化？依赖项：

<dependency>
    <groupId>org.powermock</groupId>
    <artifactId>powermock-module-junit4</artifactId>
    <version>2.0.4</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.powermock</groupId>
    <artifactId>powermock-api-mockito</artifactId>
    <version>2.0.4</version>
    <scope>test</scope>
</dependency>
        <dependency>
        <groupId>org.mockito</groupId>
        <artifactId>mockito-core</artifactId>
        <version>2.15.0</version>
        <scope>test</scope>
    </dependency>

顺便说一下，哪个版本的 mockito 与 Powermock 兼容？- 我看到使用 mockito 支持 Powermock 存在一些问题

有多种的MaxProductOfThree任务答案codility.com,其中大部分涉及排序算法.

问题是:

给出了由N个整数组成的非空零索引数组A.

问题是找到给定数组中3个元素的最大乘积.

阵列的长度在3到100,000之间

数组A的每个元素都是[-1,000..1,000]范围内的整数

    expected worst-case time complexity is O(N*log(N));

    expected worst-case space complexity is O(1), 

超出输入存储(不计入输入参数所需的存储).例:

  a[0] = -3;
  a[1] = 7;
  a[2] = 2;
  a[3] = 1;
  a[4] = 5;
  a[5] = 7;

最大乘积是[1]*a [4]*a [5] = 245

除了涉及排序的O(n log n)方法之外,是否存在线性时间解决该问题的方法？

我有一个问题,创建用于弹性搜索的TransportClient bean,compiller它说构造函数是私有的,就像那样.我怎样才能正确创建bean？这是我的配置类:

import org.elasticsearch.client.Client;
import org.elasticsearch.client.transport.TransportClient;
import org.elasticsearch.common.transport.InetSocketTransportAddress;
import org.elasticsearch.common.transport.TransportAddress;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.elasticsearch.core.ElasticsearchOperations;
import org.springframework.data.elasticsearch.core.ElasticsearchTemplate;
import org.springframework.data.elasticsearch.repository.config.EnableElasticsearchRepositories;

@Configuration
@EnableElasticsearchRepositories(basePackages = "example.spring.data.es.repository")
@ComponentScan(basePackages = { "example.spring.data.es.service" })
public class Config {

@Bean
public Client client() {
//here compiller says that the TransportClient() is private. How else i cna create the transport client?
    TransportClient client = new TransportClient();

    TransportAddress address = new InetSocketTransportAddress(
            "localhost",9200);
    client.addTransportAddress(address);
    return client;
}

@Bean
public ElasticsearchOperations elasticsearchTemplate() {
    return new ElasticsearchTemplate(client());
} …
