Spring boot应用失败，Jackson2ObjectMapperBuilder。可见性不存在

Posted 2021-04-26

在我的Spring Boot应用程序中，我有很少的依赖项：

implementation "org.springframework.boot:spring-boot-starter:$springBootVersion"
testImplementation "org.springframework.boot:spring-boot-starter-test:$springBootVersion"

应用程序无法启动：

***************************
APPLICATION FAILED TO START
***************************

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    java.lang.invoke.MethodHandleNatives.resolve(Native Method)

The following method did not exist:

    org.springframework.http.converter.json.Jackson2ObjectMapperBuilder.visibility(Lcom/fasterxml/jackson/annotation/PropertyAccessor;Lcom/fasterxml/jackson/annotation/JsonAutoDetect$Visibility;)Lorg/springframework/http/converter/json/Jackson2ObjectMapperBuilder;

The method's class, org.springframework.http.converter.json.Jackson2ObjectMapperBuilder, is available from the following locations:

    jar:file:/Users/me/.gradle/caches/modules-2/files-2.1/org.springframework/spring-web/4.3.25.RELEASE/76d29c076153e09961c8e6fd9b2d5c50bb80b902/spring-web-4.3.25.RELEASE.jar!/org/springframework/http/converter/json/Jackson2ObjectMapperBuilder.class

It was loaded from the following location:

    file:/Users/me/.gradle/caches/modules-2/files-2.1/org.springframework/spring-web/4.3.25.RELEASE/76d29c076153e09961c8e6fd9b2d5c50bb80b902/spring-web-4.3.25.RELEASE.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of org.springframework.http.converter.json.Jackson2ObjectMapperBuilder

Disconnected from the target VM, address: '127.0.0.1:57370', transport: 'socket'

Process finished with exit code 1

springBootVersion为2.2.6.RELEASE

答案

spring-boot-starter依赖项似乎不包括所需类所在的spring-web。将implementation "org.springframework.boot:spring-boot-starter-web:$springBootVersion"添加到您的Gradle文件中，然后重试。
