Spring Data web pagination "page" parameter not working
提问by Biju Kunjummen
I'm trying to get Spring Data's web pagination working. It's described here:
我试图让 Spring Data 的网页分页工作。它在这里描述：
Here's my Java (Spring Web MVC @Controller handler method):
这是我的 Java（Spring Web MVC @Controller 处理程序方法）：
@RequestMapping(value = "/list", method = RequestMethod.GET)
public String list(
@PageableDefaults(value = 50, pageNumber = 0) Pageable pageable,
Model model) {
log.debug("Params: pageNumber={}, pageSize={}",
pageable.getPageNumber(), pageable.getPageSize());
...
}
And here's my Spring configuration:
这是我的 Spring 配置：
<mvc:annotation-driven>
<mvc:argument-resolvers>
<bean class="org.springframework.data.web.PageableArgumentResolver" />
</mvc:argument-resolvers>
</mvc:annotation-driven>
(It appears that the configuration above is the way to do this now; the configuration approach described in the link is deprecated.)
（似乎上面的配置是现在执行此操作的方法；不推荐使用链接中描述的配置方法。）
When I actually try to control the pagination using the pageand page.sizeparameters, the latter works just fine, but the former doesn't. For example, if I hit
当我实际尝试使用page和page.size参数控制分页时，后者工作得很好，但前者不行。例如，如果我打
http://localhost:8080/myapp/list?page=14&page.size=42
the log output is
日志输出是
Params: pageNumber=0, pageSize=42
So I know that the argument resolver is kicking in, but not sure why it's not resolving the page number. I've tried a bunch of other param names (e.g. page.number, pageNumber, page.num, etc.) and none of them work.
所以我知道参数解析器正在启动，但不确定为什么它不解析页码。我尝试了一堆其他参数名称（例如 page.number、pageNumber、page.num 等），但没有一个起作用。
Is this working for anybody else?
这对其他人有用吗？

the page parameter is actually a bit non-intuitive - page.pageand not page, changing to page.pageshould get things to work.
page 参数实际上有点不直观 -page.page而不是page，更改为page.page应该可以使事情正常工作。

Looking into the PageableArgumentResolverI found that prefixand separatorare configurable, so you can configure the class not to have it.
查看PageableArgumentResolver我发现prefix并且separator是可配置的，因此您可以将类配置为不具有它。
public class PageableArgumentResolver implements WebArgumentResolver {
private static final Pageable DEFAULT_PAGE_REQUEST = new PageRequest(0, 10);
private static final String DEFAULT_PREFIX = "page";
private static final String DEFAULT_SEPARATOR = ".";
in my @Configuration class I did something different to achieve using page, size,sortand sortDiras default.
在我@Configuration类我做了不同的使用来实现page，size，sort和sortDir为默认值。
@Override
public void addArgumentResolvers(List<HandlerMethodArgumentResolver> argumentResolvers) {
PageableArgumentResolver resolver = new PageableArgumentResolver();
resolver.setPrefix("");
resolver.setSeparator("");
argumentResolvers.add(new ServletWebArgumentResolverAdapter(resolver));
}
Now this works
现在这有效
http://:8080/myapp/list?page=14&size=42
http://:8080/myapp/list?page=14&size=42

You can override parameters if you want by doing:
如果需要，您可以通过执行以下操作来覆盖参数：
<mvc:annotation-driven>
<mvc:argument-resolvers>
<bean class="org.springframework.data.web.PageableHandlerMethodArgumentResolver">
<property name="oneIndexedParameters" value="true"></property>
<property name="pageParameterName" value="page"></property>
<property name="sizeParameterName" value="size"></property>
</bean>
</mvc:argument-resolvers>
</mvc:annotation-driven>
