无法绑定属性

Question

我已经将Spring从1.5.6版本更新到了2.0.0，并且出现了很多问题。其中之一是题目中的问题。我有一个有属性的类

@Data
@ConfigurationProperties("eclipseLink")
public class EclipseLinkProperties { ... }

我在配置中使用的

@Configuration
@EnableConfigurationProperties(EclipseLinkProperties.class)
public class WebDatasourceConfig { ... }

在编译过程中，他抛弃了我

2018-03-18 18:44:58.560  INFO 3528 --- [           main] trationDelegate$BeanPostProcessorChecker : Bean 'org.springframework.boot.context.properties.ConversionServiceDeducer$Factory' of type [org.springframework.boot.context.properties.ConversionServiceDeducer$Factory] is not eligible for getting processed by all BeanPostProcessors (for example: not eligible for auto-proxying)

2018-03-18 18:44:58.575  WARN 3528 --- [           main] ConfigServletWebServerApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'webDatasourceConfig': Unsatisfied dependency expressed through field 'eclipseLinkProperties'; nested exception is org.springframework.boot.context.properties.ConfigurationPropertiesBindException: Error creating bean with name 'eclipseLink-com.web.web.config.properties.EclipseLinkProperties': Could not bind properties to 'EclipseLinkProperties' : prefix=eclipseLink, ignoreInvalidFields=false, ignoreUnknownFields=true; nested exception is org.springframework.boot.context.properties.source.InvalidConfigurationPropertyNameException: Configuration property name 'eclipseLink' is not valid

这意味着

Configuration property name 'eclipseLink' is not valid

在Spring更新之前，一切都成功了。

Answer 1

eclipseLink不是有效的前缀。作为在文档中描述，烤箱应该被使用而不是camelCase。所以你的前缀应该是eclipse-link而不是eclipseLink。

Answer 2

Spring 2.0不支持Camel情况。它将引发InvalidConfigurationPropertyNameException:配置属性名称‘*’无效。

Answer 3

你可以改变：

@ConfigurationProperties("eclipseLink")

至：

@ConfigurationProperties("eclipselink")

您不需要更改属性文件。这将避免错误。Spring将能够找到eclipseLink.*属性。
