我下载了新的Eclipse Luna(版本4.4)并改为Dark Theme,但代码编辑器没有改变.看屏幕截图:

我在MAC,Windows和Linux上试过这个,结果总是一样的.

我有以下命令让OpenSSL生成私钥和公钥:

openssl genrsa –aes-128-cbc –out priv.pem –passout pass:[privateKeyPass] 2048

和

openssl req –x509 –new –key priv.pem –passin pass:[privateKeyPass] -days 3650 –out cert.cer

但是没有为第一个命令工作我得到以下错误:

usage: genrsa [args] [numbits]
 -des            encrypt the generated key with DES in cbc mode
 -des3           encrypt the generated key with DES in ede cbc mode (168 bit key)
 -seed
                 encrypt PEM output with cbc seed

                 encrypt PEM output with cbc aes

                 encrypt PEM output with cbc camellia

我需要在JAVA中对我的XML消息进行数字签名:生成的XML签名应具有以下格式:

<Signature xmlns="http://www.w3.org/2000/09/xmldsig#">
<SignedInfo>
<CanonicalizationMethod Algorithm="http://www.w3.org/2001/10/xml-exc-c14n#" />
<SignatureMethod Algorithm="http://www.w3.org/2001/04/xmldsig-more#rsa-sha256" />
<Reference URI="">
<Transforms>
<Transform Algorithm="http://www.w3.org/2000/09/xmldsig#enveloped-signature"/>

谁能提供一些代码帮助？

编辑:

我想出了这段代码:

private static Document sign(Document doc) throws InstantiationException, IllegalAccessException, ClassNotFoundException,
            NoSuchAlgorithmException, InvalidAlgorithmParameterException, KeyException, MarshalException, XMLSignatureException,
            FileNotFoundException, TransformerException {

        String providerName = System.getProperty("jsr105Provider", "org.jcp.xml.dsig.internal.dom.XMLDSigRI");

        XMLSignatureFactory fac = XMLSignatureFactory.getInstance("DOM", (Provider) Class.forName(providerName).newInstance());

        Reference ref = fac.newReference("", fac.newDigestMethod(DigestMethod.SHA256, null));

        // Create the SignedInfo
        SignedInfo si = fac.newSignedInfo(
                fac.newCanonicalizationMethod(CanonicalizationMethod.EXCLUSIVE, (C14NMethodParameterSpec) null),
                fac.newSignatureMethod(SignatureMethod.RSA_SHA1, null), …

I have list of Joda-Time intervals

List<Interval> intervals = new ArrayList<Interval>();

and another Joda-Time interval (search time interval), like on the picture below.

I need to write Java function that finds the holes in time and returns List<Interval> with the red intervals.

我有Joda-Time Interval对象列表.

List<Interval> intervals = new ArrayList<Interval>();

如何在每个间隔的开始日期对间隔进行排序.间隔不重叠

我通过编译项目来获得疯狂的排列数量.如果我设置选项:

<set-property name="user.agent" value="gecko1_8" />

我得到:编译1008个排列

如果我设置:

<set-property name="locale" value="de"/>
<set-property name="user.agent" value="gecko1_8" />

我得到:编译36个排列

我正在尝试使用 spring boot poject 配置 gradle id 'jvm-test-suite' 插件

plugins {
    id 'java'
    id 'jvm-test-suite'
    id 'org.springframework.boot' version '3.0.0'
    id 'io.spring.dependency-management' version '1.1.0'

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '17'

repositories {
    mavenCentral()
}

ext {
    set('testcontainersVersion', "1.17.6")
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-data-mongodb'
    implementation 'org.springframework.boot:spring-boot-starter-web'
}

dependencyManagement {
    imports {
        mavenBom "org.testcontainers:testcontainers-bom:${testcontainersVersion}"
    }
}

testing {
    suites {
        configureEach {
            useJUnitJupiter()
            dependencies {

            }
        }
        test {


        }

        integrationTest(JvmTestSuite) …

我通过任何类型的验证突然得到这个例外.
