java - 组件需要名为 'org.springframework.boot.context.internalConfigurationPropertiesBinder' 的 bean，但无法找到

Question

我有一个带有 Gradle 的 Spring Boot 多模块项目。运行应用程序时，我收到以下错误:-

Description:

A component required a bean named 'org.springframework.boot.context.internalConfigurationPropertiesBinder' that could not be found.


Action:

Consider defining a bean named 'org.springframework.boot.context.internalConfigurationPropertiesBinder' in your configuration.

该项目有一个根项目，该项目有一个子项目“GetAssociationService”

根项目 - build.gradle

    plugins {
        id 'org.springframework.boot' version '2.2.5.RELEASE'
        id 'io.spring.dependency-management' version '1.0.9.RELEASE'
        id 'java'
        id 'com.github.johnrengelman.shadow' version '5.2.0'
    }

bootJar { enabled = false }

jar { enabled = true }

subprojects {
    group = 'org.qmetech'
    version = '1.0.0'
    sourceCompatibility = '1.8'
    targetCompatibility = '1.8'
    apply plugin: 'org.springframework.boot'
    apply plugin: 'io.spring.dependency-management'
    apply plugin: 'com.github.johnrengelman.shadow'
    apply plugin: 'java'
}

repositories { mavenCentral ( ) }

ext { set ( 'springCloudVersion' , "Hoxton.SR3" ) }

dependencies {
    testImplementation ( 'org.springframework.boot:spring-boot-starter-test' ) {
        exclude group: 'org.junit.vintage' , module: 'junit-vintage-engine'
    }
}

ext.libraries = [
        commonlibraries: [ 'org.springframework.boot:spring-boot-starter:2.2.5.RELEASE' ,
                      'org.springframework.cloud:spring-cloud-function-context' ,
                      'org.springframework.cloud:spring-cloud-function-adapter-aws:2.0.1.RELEASE' ,

]

dependencyManagement {
    imports {
        mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
    }
}

test { useJUnitPlatform ( ) }
ChildProject - build.gradle

sourceCompatibility = 1.8
targetCompatibility = 1.8

repositories {
    mavenCentral()
}

springBoot {
    mainClassName = 'org.qmetech.GetAssociationService'
}

dependencies {
    dependencies {
        compile libraries.commonlibraries
        implementation 'org.springframework.boot:spring-boot-starter-data-mongodb'
    }
}

UserRepository.java

package org.qmetech.repository;

import org.qmetech.domain.User;
import org.springframework.data.mongodb.repository.MongoRepository;
import org.springframework.stereotype.Repository;

@Repository
public interface UserRepository extends MongoRepository<User, Integer> { }

AssociationService.java

package org.qmetech.service;

import org.qmetech.domain.User;
import org.qmetech.repository.UserRepository;
import org.springframework.stereotype.Component;

import java.util.List;
import java.util.function.Function;

@Component
public class AssociationService implements Function<String, List<User>> {

    private final UserRepository userRepository;

    public AssociationService(UserRepository userRepository) {
        this.userRepository = userRepository;
    }

    @Override
    public List<User> apply(String uppercaseRequest) {
        List<User> users = userRepository.findAll();
        return users;
    }
}

谁能告诉我我做错了什么吗？

谢谢!

Answer 1

我也遇到了这个问题，就我而言，“org.springframework.boot”版本中存在问题。我将版本更改为 2.1.6 Release。然后问题就解决了。
