将@PageableDefault与Spring数据REST一起使用

@PageableDefault的文档说明：

注记时设置默认值的注释

org.springframework.data.domain.Pageable

进入控制器方法

使用SpringDataREST时，有没有一种方法可以在不定义控制器的情况下设置默认值

在存储库中设置PageableDefault（如下所示）似乎不起作用

Page<Player> findAll(@PageableDefault(size=5) Pageable pageable);

Page findAll（@PageableDefault（size=5）Pageable-Pageable）；

弹簧和弹簧护套的解决方案 您可以扩展RepositoryRestConfigurerAdapter配置以设置默认页面大小：

@Configuration
public class RepositoryRestConfig extends RepositoryRestConfigurerAdapter {

    @Override
    public void configureRepositoryRestConfiguration(RepositoryRestConfiguration repositoryRestConfiguration) {
            repositoryRestConfiguration.setDefaultPageSize(5);
    }
}

仅适用于Spring引导的解决方案 您可以在application.properties中设置默认大小： 其他Spring数据属性：

使用RestResource注释存储库方法时，可以通过截取请求并添加默认参数值（如果不存在）自定义页面大小：

然后为特定url模式注册此筛选器：

@Configuration
public class RestResourcePaginationConfig {

    @Bean
    public FilterRegistrationBean<RestResourceDefaultPaginationFilter> paginationFilter() {
        FilterRegistrationBean<RestResourceDefaultPaginationFilter> registrationBean = new FilterRegistrationBean<>();
        registrationBean.setFilter(new RestResourceDefaultPaginationFilter());
        registrationBean.addUrlPatterns("/myEntities/search/rest-resource-endpoint");
        return registrationBean;
    }
}

@配置
公共类RestResourcePaginationConfig{
@豆子
公共筛选器注册bean分页筛选器（）{
FilterRegistrationBean registrationBean=新的FilterRegistrationBean（）；
setFilter（新RestResourceDefaultPaginationFilter（））；
addUrlPatterns（“/myenties/search/rest资源端点”）；
返回注册bean；
}
}

当您想要对alexbt描述的更一般的选项有例外时，这很方便。

我的错，我只想到spring boot添加了一个非spring boot解决方案Works，但为所有存储库和所有方法设置了默认值。我会等待其他答案，如果没有其他解决方案，我会接受这个答案。ThanksHow是否将默认值设置为未分页？
