最近我们开始在我们的项目中使用Lombok功能.我们有@DataDomain对象的注释,因为运行时有一些hashCode()由Lombok api提供的方法抛出的异常.后来,当我添加@Setter而@Getter不是@Data,我没有看到任何问题.

问题1:请问龙目@Data覆盖像一类的现有方法hashCode()和toString()？

问题2:为什么hashCode()在这里出问题？

在调用下游RESTful服务时,我们看到太多"连接过早关闭并由同行重置"错误,即使在将Springboot版本升级到最新的专家建议之后也是如此.

我们试图重现它,但无法在dev中重现.它发生在负载测试中,当应用程序负载过重时.

任何帮助和建议表示赞赏,提前谢谢.

我正在使用Gradle在我的项目中生成jaxb类.每个东西都工作正常,但在编组jaxb对象时,我们在输出xml中随机看到不同的名称空间前缀,如ns1,ns2 .. 但我们不想要这个,并希望为每个命名空间指定特定的命名空间前缀.我查了这里,发现该链接15772478说,我们必须有xmlns的元件封装,信息类,我怎么能说XJC绑定编译器添加的xmlns元素与prifixes和的namespaceURI？下面是我必须从模式生成Jaxb类的gradle配置.

  ant.taskdef(name: 'xjc', classname: 'com.sun.tools.xjc.XJCTask',  classpath:configurations.jaxb.asPath)
  ant.jaxbTargetDir = jaxbTargetDir

  ant.xjc(destdir: '${jaxbTargetDir}', binding: 'xjc-bindings/bindings.jaxb', extension: true) {
  //arg(value: '-npa')
  arg(value: '-readOnly')
  arg(value: file('src/main/webapp/schemas/primary1.xsd'))
  arg(value: file('src/main/webapp/schemas/primary2.xsd'))
  arg(value: file('xjc-bindings/xjc-a.xsd'))
  arg(value: file('xjc-bindings/xjc-b.xsd'))
 }

示例由xjc绑定生成的package-info.java.

@XmlSchema(namespace = "urn:neustar:names:decedm:1.0")
package biz.neustar.dece.xml.jaxb.decedm;
import javax.xml.bind.annotation.XmlSchema;

我期待如下的package-info类.

@XmlSchema(namespace = "<someuri>", 
 elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED,
 xmlns={
      @XmlNs(prefix="someprefix" , namespaceURI = "<some uri>")
 })
 package biz.neustar.dece.xml.jaxb.core;
 import javax.xml.bind.annotation.XmlNs;
 import javax.xml.bind.annotation.XmlSchema;

有人可以建议我实现这个需要什么配置？我不想使用NamespacePrefixMapper来指定前缀.
