我想检查方法中的空值

@Override
 public void updateFooFromNonNullAttributesOfDto(FooDto fooDto, Foo foo) {
        if ( fooDto== null ) {
            return;
        }
        if ( fooDto.getBar() != null ) {
            site.setBar( fooDto.getBar() );
        }
         if ( fooDto.getBaz() != null ) {
            site.setBar( fooDto.getBaz() );
        }
}

当我使用

@Mapper( NullValueCheckStrategy.ALWAYS)

它检查所有方法，但我只想检查一种......如何解决这个问题？

我有Kotlin界面

interface FileSystem {
    suspend fun getName(path: Path): List<String>
}

我怎么能用Java调用它？什么是

Continuation <? super List<String>>

你能告诉我这些警告与什么有关吗？

Swagger 扫描包裹。到目前为止，并不是所有的类型都被标注了注释

如何正确使用带有日期间隔的查询

 @SqlUpdate("delete fromlogin where created < now() - ':days days' :: interval")
 void deleteOldLogin(@Bind("days") Period days);

我如何在何处创建动态

public interface ThingDAO {
   @SqlQuery("SELECT * FROM things <where>)
   List<Thing> findThingsWhere(@Define("where") String where);
}

JDBI 如何在防止 SQL 注入的同时动态创建 WHERE 子句？

但它实际上并不适用于 JDBI3

我的项目结构如

-parent
--web
--server
----moduleA
----moduleB
----module?
----main

我只想部署来自 mweb 模块的 WAR 和来自主模块的 EAR 但现在部署所有 jar 等

我必须如何配置我的 Maven？

告诉我如何正确配置Feign和Spring Pageable的工作这里是我的Feign设置

feign:
  okhttp:
    enabled: true
  autoconfiguration:
    jackson:
      enabled: true
  client:
    config:
      default:
        connectTimeout: ${FEIGN_DEFAULT_CONNECT_TIMEOUT:10000}
        readTimeout: ${FEIGN_DEFAULT_READ_TIMEOUT:60000}
        loggerLevel: full
        errorDecoder: ru.core.config.TokenErrorDecoder
        retryer: ru.service.SudisTokenService

我的假客户

@FeignClient(name = "BaseCaseFeignClient", url = "${feign.services.host-backend.url}")
public interface BaseCaseFeignClient {
    @GetMapping("/api/cases/base")
    Page<BaseCaseEntityDto> getBaseCases(@SpringQueryMap BaseCaseEntityFilter filter, Pageable pageable);

    @PostMapping("/api/cases/base/search")
    Page<FoundRecordDto> searchCases(@RequestBody FilterSpecification filter, @SpringQueryMap Pageable pageable);
}

获取请求工作正常。发布请求时出现问题。我收到以下错误

"No property caseOpenDttm: DESC found for type BaseCaseEntity!"

在这种情况下，该项目根本不会被组装。

Page<FoundRecordDto> searchCases(@RequestBody FilterSpecification filter, Pageable pageable);

Caused by: java.lang.IllegalStateException: Method has too many Body parameters: public abstract org.springframework.data.domain.Page ru..BaseCaseFeignClient.searchCases(ru.ilter.shared.basecase.search.FilterSpecification,org.springframework.data.domain.Pageable)

CSSResource 接口

public interface AppResources extends ClientBundle {
    public static final AppResources INSTANCE = GWT.create(AppResources.class);

    interface Style extends CssResource {
        String login();
    }

    @Source("css/style.gss")
    Style style();

    @Source("images/logo.png")
    ImageResource logo();
}

样式

.login {
    width: 100%;
    height: 100%;
}

.login .panel-body {
    text-align: center;
}

.login .loginWrapper {
    display: flex;
    justify-content: center;
    align-items: center;
    width: 100%;
    height: 100%;
}

.login .input-group {
    padding-bottom: 10px;
    width: 300px;
}

.login .input-group-addon {
    width: 100px;
}

当您尝试编译时出现错误

我在父母POM中宣布

<dependencyManagement>
        <dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-lang3</artifactId>
            <version>${commons-lang3.version}</version>
            <scope>compile</scope>
        </dependency>
</dependencyManagement>

此外,孩子使用pom

<dependencies>
        <dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-lang3</artifactId>
        </dependency>
</dependencies>

一切正常吗？但是当我使用type = pom的这种依赖时

<dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.jboss.spec</groupId>
                <artifactId>jboss-javaee-7.0</artifactId>
                <version>${jboss-javaee-7.0.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
</dependencyManagement>

我有错误
