我想在我的@BeforeTest方法中将一些Web范围注册到spring上下文中.但事实证明,春天的背景仍然存在null.

如果我改变,测试运行正常@BeforeMethod.我想知道如何访问上下文@BeforeTest,因为我不希望为每个测试方法重复范围注册代码.

以下是我的代码片段.

public class MyTest extends MyBaseTest {
    @Test public void someTest() { /*...*/ }
}

@ContextConfiguration(locations="/my-context.xml")
public class MyBaseTest extends AbstractTestNGSpringContextTests {
    @BeforeTest public void registerWebScopes() {
        ConfigurableBeanFactory factory = (ConfigurableBeanFactory)
                this.applicationContext.getAutowireCapableBeanFactory();
        factory.registerScope("session", new SessionScope());
        factory.registerScope("request", new RequestScope());
    }   

    /* some protected methods here */
}

这是运行测试时的错误消息:

FAILED CONFIGURATION: @BeforeTest registerWebScopes
java.lang.NullPointerException
    at my.MyBaseTest.registerWebScopes(MyBaseTest.java:22)

我有一个包含70个元素的列表.

例如:

List<Long> dbList = new ArrayList<Long>();

dbList有70条记录.如果我将所有记录发送到MySql中的查询,则需要很长时间.所以现在我想每次向数据库查询发送10个元素.所以我需要以10为间隔迭代列表.我该怎么做？这是避免长时间使用的好方法IN.

SQL查询

select model.boothId, model.panchayat.panchayatId
from Table1 model
where model.panchayat.panchayatId in(:locationValues)
  and model.publicationDate.publicationDateId in (:publicationDateIdsList)
  and model.constituency.id = :id group by model.panchayat.panchayatId

我有一个项目,其中包含多个子项目的共享资源; 即,以及Java代码,它包含CSS和JavaScript.

我的子项目使用maven程序集插件打包为jar.由于某些原因,这些不包括父库中的css和js资源.

所以我的问题很简单:我如何配置项目以便发生这种情况？我不希望儿童项目成为战争; 它们是作为独立jar运行的dropwizard(/ jetty)项目.

编辑 - 我应该明确表示资源包含在父项目的jar中; 只有当汇编(在子项目中)包含他们以某种方式丢失的jar时.

这似乎应该很简单,但我无法让它工作.我正在尝试设置distributionType包装器任务的属性,但它不起作用:

task wrapper(type: Wrapper) {
    gradleVersion = '4.1'
    distributionType = DistributionType.ALL
}

当我尝试运行包装器任务时,我收到以下错误:

$ gradle wrapper

我有一个带有TreeMap的可序列化对象.

Map<String, Dogs> dogsByNames = Maps.newTreeMap(); // guava style

到目前为止,一切都很好.现在忽略键的情况是必要的:

Map<String, Dogs> dogsByNames = Maps.newTreeMap(String.CASE_INSENSITIVE_ORDER);

这不起作用,因为String.CASE_INSENSITIVE_ORDER不是serialzable:

com.google.gwt.user.client.rpc.SerializationException:类型'java.lang.String $ CaseInsensitiveComparator'未包含在可由此SerializationPolicy序列化的类型集中,或者无法加载其Class对象.出于安全考虑,此类型不会被序列化:instance = java.lang.String$CaseInsensitiveComparator@f26f68

所以我创建了自己的一个:

private static abstract class MyComparator<T>
    implements
        Comparator<T>, // extends Ordering<T> do not work
        IsSerializable { // Serializable do not work
}

public static final MyComparator<String> CASE_INSENSITIVE_ORDER = new MyComparator<String>() {
    @Override
    public int compare(final String left, final String right) {
        if (null == left) {
            return (null == right) ? 0 : -1;
        } else if (null == …

我正在编写测试以验证我的方法的合同,例如,参数不能null,int参数必须是正的等等.当违反合同时,抛出的异常类型反映了它失败的原因,例如NullPointerException或IllegalArgumentException.有时我不关心这两个中的哪一个被抛出,只有其中一个被抛出.(是的,我应该测试确切的异常类型,但请耐心等待...)

我可以使用JUnit @Test(expected = RuntimeException.class)(因为RuntimeException它是最接近的公共父IAE和NPE),但这是过于通用的,因为被测试的方法可能会引发其他一些RuntimeException.

相反,我正在尝试使用JUnit的ExpectedExceptions类.

这是一个完整的例子:

import org.hamcrest.CoreMatchers;
import org.junit.Rule;
import org.junit.Test;
import org.junit.rules.ExpectedException;
import static org.hamcrest.CoreMatchers.anyOf;

public class ParameterViolationTest {
    private Target target = new Target();

    @Rule
    public ExpectedException expected = ExpectedException.none();

    @Test
    public void parameterViolation() {
        expected.expect(anyOf(
                CoreMatchers.<Class<? extends Exception>>
                        equalTo(NullPointerException.class),
                CoreMatchers.<Class<? extends Exception>>
                        equalTo(IllegalArgumentException.class)));

        // Null parameter violates contract, …

例如,假设我有一个Maven构建文件,其依赖项位于两个不同的存储库中:

<repository>
    <id>id1</id>
    <name>id1</name>
    <url>http://localhost/mavenRepo/repository1</url>
</repository>

<repository>
    <id>id2</id>
    <name>id2</name>
    <url>http://localhost/mavenRepo/repository2</url>
</repository>

有一个来自第一个存储库的依赖项,另一个来自第二个存储库.我怎样才能做到这一点？
