我的控制器

@RestController
public class CheckUserDataRestController {
    private final UserSearchService userSearchService;
    @Autowired
    public CheckUserDataRestController(final UserSearchService userSearchService) {
        this.userSearchService = userSearchService;
    }
...
}

初始化 bean 服务

@Service("userSearchService")
public class UserSearchServiceImpl implements UserSearchService {
    private final UserRepository userRepository;
    private final AuthorizationService authorizationService;
    @Autowired
    public UserSearchServiceImpl(
            @NotNull final UserRepository userRepository,
            @NotNull final AuthorizationService authorizationService
    ) {
        this.userRepository = userRepository;
        this.authorizationService = authorizationService;
    }
...
}

初始化另一个服务 bean

@Service("authorizationService")
public class AuthorizationServiceImpl implements AuthorizationService {
    private final UserSearchService userSearchService;
    @Autowired
    public AuthorizationServiceImpl(final UserSearchService userSearchService) …

I create an application in Spring Boot 2.0.0. I use HikariCP by default. The application.yml file for the PostgreSQL database looked like this

spring:
  datasource:
    driver-class-name: org.postgresql.Driver
    jdbcUrl: jdbc:postgresql:database
    username: root
    password: root
    type: com.zaxxer.hikari.HikariDataSource
    # Hikari
    poolName: SpringBootHikariCP
    maximumPoolSize: 5
    minimumIdle: 3
    maxLifetime: 2000000
    connectionTimeout: 30000
    idleTimeout: 30000
    pool-prepared-statements: true
    max-open-prepared-statements: 250
    connection-test-query: SELECT 1
eclipse-link:
  database-platform: org.eclipse.persistence.platform.database.PostgreSQLPlatform
  generate-dll: true
  show-sql: true
  weaving: static

The PostgreSQL application works without a problem. After I tried to change the database …

我有build.gradle该项目的主文件

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${spring_boot_version}")
    }
}

def javaProjects = subprojects.findAll {
    it.name in ["common", "core", "web", "app"]
}

allprojects {
    apply plugin: 'idea'
    apply plugin: 'eclipse'

    repositories {
        jcenter()
    }
}

idea {
    project {
        jdkName = "1.8"
        languageLevel = "1.8"
        vcs = "Git"
    }
}

configure(javaProjects) {
    apply plugin: 'java'
    apply plugin: 'io.spring.dependency-management'
    apply plugin: 'findbugs'

    sourceCompatibility = 1.8
    targetCompatibility = 1.8

    dependencies {
        ...
    }
}

和模块的build.gradle文件app …

我在对象中有一个变量：

private final Map<Long, ? extends MovieInfoDTO> bElementsToAdd = new HashMap<>();

使用Builder模式中的方法我想完成这个地图。

public Builder withElementsToAdd(@Nullable final Map<Long, ? extends MovieInfoDTO> elementsToAdd) {
     this.bElementsToAdd.clear();
     if(elementsToAdd != null) {
         this.bElementsToAdd.putAll(elementsToAdd);
     }
     return this;
}

但是，我收到一个错误。

    putAll
(java.util.Map<? extends java.lang.Long,? extends capture<? extends com.jonki.popcorn.common.dto.movie.MovieInfoDTO>>)
in Map cannot be applied
to
(java.util.Map<java.lang.Long,capture<? extends com.jonki.popcorn.common.dto.movie.MovieInfoDTO>>)

如何更正这种补充地图的方法？
