使用springdatajpa查询数据分页，默认springpagination下标分页从0开始，前端对接一般从1页开始，其中有Configurespring.data.web.pageable.one-indexed-parameters，默认为false，即从下标0开始，改为true从1开始。但是改了之后就不行了。经查，问题记录如下：VersionSpringbootversion-2.6.4原因是使用了@EnableSpringDataWebSupport注解，默认会加载SpringDataWebConfiguration.class配置类的配置，里面定义了一个bean@BeanpublicPageableHandlerMethodArgumentResolverpageableResolver(){PageableHandlerMethodArgumentResolverpageableResolver=newPageableHandlerMethodArgumentResolver(sortResolver.get());customizePageableResolver(pageableResolver);returnpageableResolver;}而上面的spring.data.web.pageable.one-indexed-parameter自动注入配置是@Bean@ConditionalOnMissingBean.properties.getPageable();.getSizeParameter());resolver.setOneIndexedParameters(pageable.isOneIndexedParameters());resolver.setPrefix（可分页.getPrefix());resolver.setQualifierDelimiter(pageable.getQualifierDelimiter());resolver.setFallbackPageable(PageRequest.of(0,pageable.getDefaultPageSize()));resolver.setMaxPageSize(pageable.getMaxPageSize());};}然后SpringDataWebAutoConfiguration.class在自动配置类上有一个@ConditionalOnMissingBean(PageableHandlerMethodArgumentResolver.class)。如果这个bean存在，则不会自动加载，而且这个bean定义在SpringDataWebConfiguration类中，形成冲突解决办法就是自己定义一个config，其中在定义一个PageableHandlerMethodArgumentResolverCustomizer的bean@Configuration@EnableConfigurationProperties(SpringDataWebProperties.class)publicclassConfig{@Bean@ConditionalOnMissingBeanpublicPageableHandlerMethodArgumentResolverCustomizerpageableCustomizer(SpringDataWebPropertiesproperties){return(resolver)->{Pageablepageable=properties.getPageable();resolver.setPageParameterName(pageable.getPageParameter());resolver.setSizeParameterName(pageable.getSizeParameter());resolver.setOneIndexedParameters(pageable.isOneIndexedParameters());resolver.setPrefix(pageable.getPrefix());resolver.setQualifierDelimiter(pageable.getQualifierDelimiter());resolver.setFallbackPageable(PageRequest.of(0,pageable.getDefaultPageSize()));resolver.setMaxPageSize(pageable.getMaxPageSize());};}}
