Question

我正在开发一个Spring Boot REST应用程序。但是，每当我尝试启动它时，都会收到以下错误：

Error creating bean with name 'requestMappingHandlerAdapter' defined in class path resource [org/springframework/boot/autoconfigure/web/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter]: Factory method 'requestMappingHandlerAdapter' threw exception; nested exception is java.lang.NoSuchFieldError: defaultReader

现在，从这个question（和堆栈），我收集它是杰克逊用于转换的JsonSmart和/或JsonPath的问题。

我认为它可能是某种依赖性问题;但是，我已尝试切换版本并手动引入依赖项（例如Spring Data）来覆盖启动器默认值。没有成功。这是我的gradle文件：

  buildscript {
    ext {
        springBootVersion = '1.5.9.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'

group = 'com.midamcorp'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8

repositories {
    mavenCentral()
}


dependencies {
testCompile('junit:junit:4.11')
    testCompile('org.springframework.boot:spring-boot-starter-test')
    compile('org.springframework.boot:spring-boot-starter-data-jpa')
    compile('org.springframework.boot:spring-boot-starter-web')
    compile('org.springframework.boot:spring-boot-starter-data-rest')
    compile('org.springframework.boot:spring-boot-starter-security')
    compile('org.springframework.security.oauth:spring-security-oauth2:2.2.1.RELEASE')
        compile('org.springframework.security:spring-security-jwt:1.0.9.RELEASE')
compile('org.modelmapper:modelmapper:0.7.5')
    compile('org.hibernate:hibernate-java8:5.0.0.Final')
compile('com.microsoft.sqlserver:mssql-jdbc:6.1.0.jre8')



}

任何建议表示赞赏。感谢。
