问题描述
我正在尝试在Spring Boot中测试Reactive Controller，但即使接收的字节流正常，也无法反序列化返回的对象，如以下代码所示...
@Test
public void testListTemp(@Autowired HypermediaWebTestClientConfigurer configurer) {
Page<T> page = new PageImpl<T>(Arrays.asList(getEntity()),PageRequest.of(0,7),1);
when(getRepository().findAll(any(SearchQuery.class),any(Pageable.class))).thenReturn(Mono.just(page));
//@formatter:off
WebTestClient
.bindToController(getController())
.argumentResolvers((argsConfigurer) -> {
Integer MAX_PAGE_SIZE = 100;
ReactivePageableHandlerMethodArgumentResolver pageableResolver = new ReactivePageableHandlerMethodArgumentResolver();
pageableResolver.setMaxPageSize(MAX_PAGE_SIZE);
pageableResolver.setFallbackPageable(SearchQuery.getDefaultPageable());
argsConfigurer.addCustomresolver(pageableResolver);
}).build()
.mutateWith(configurer)
.get()
.uri(getBaseUri()+"/")
.accept(MediaTypes.HAL_JSON)
.exchange()
.expectBody(String.class)
.consumeWith(result -> {
String model = result.getResponseBody();
System.err.println("model: " + model);
});
//@formatter:on
}
...其中的型号：
{
"links":[
{
"rel":"self","href":"/test/exampleRoot/example/?includedDeleted=false&langCode=en-US&page=0&size=7","title":"Misma página"
},{
"rel":"first","title":"Primera página"
},{
"rel":"prev","title":"Página previa"
},{
"rel":"next","title":"Siguiente página"
},{
"rel":"last","title":"Última página"
},{
"rel":"page-1","title":"1"
},{
"rel":"create","href":"/test/exampleRoot/example/?langCode=en-US"
}
],"content": [
{
"createdBy":null,"createdDate":null,"lastModifiedBy":null,"lastModifiedDate":null,"deletedBy":null,"deletedDate":null,"businessId":2,"field01":"FieldE2_01","field02":2,"links":[
{
"rel":"self","href":"/test/exampleRoot/example/2?langCode=en-US&includeDeleted=false"
},{
"rel":"all","href":"/test/exampleRoot/example/"
},{
"rel":"delete","href":"/test/exampleRoot/example/2"
},{
"rel":"update","href":"/test/exampleRoot/example/2?langCode=en-US"
}]
}],"page":
{
"size":7,"totalElements":1,"totalPages":1,"number":0
}
}
但是在以下代码中不起作用：
@Test
public void testListTemp(@Autowired HypermediaWebTestClientConfigurer configurer) {
Page<T> page = new PageImpl<T>(Arrays.asList(getEntity()),any(Pageable.class))).thenReturn(Mono.just(page));
WebTestClient
.bindToController(getController())
.argumentResolvers((argsConfigurer) -> {
Integer MAX_PAGE_SIZE = 100;
ReactivePageableHandlerMethodArgumentResolver pageableResolver = new ReactivePageableHandlerMethodArgumentResolver();
pageableResolver.setMaxPageSize(MAX_PAGE_SIZE);
pageableResolver.setFallbackPageable(SearchQuery.getDefaultPageable());
argsConfigurer.addCustomresolver(pageableResolver);
}).build()
.mutateWith(configurer)
.get()
.uri(getBaseUri()+"/")
.accept(MediaTypes.HAL_JSON)
.exchange()
.expectBody(new TypeReferences.PagedModelType<ExampleDto>() {})
.consumeWith(result -> {
PagedModel<ExampleDto> model = result.getResponseBody();
System.err.println("model: " + model);
});
//@formatter:on
}
返回的对象在哪里：
PagedResource { content: [],Metadata: Metadata { number: 0,total pages: 1,total elements: 1,size: 7 },links: }
关于您的信息，这里有ExampleDto类和层次结构的根
package net.crezco.api.example;
import javax.validation.constraints.Positive;
import javax.validation.constraints.Size;
import com.fasterxml.jackson.annotation.JsonTypeInfo;
import lombok.Getter;
import lombok.NoArgsConstructor;
import lombok.Setter;
import net.crezco.api.CzcDto;
@Getter
@Setter
@NoArgsConstructor
@JsonTypeInfo(use = JsonTypeInfo.Id.CLASS)
public class ExampleDto extends CzcDto<ExampleDto> {
@Size(max = 20)
private String field01;
@Positive
private Integer field02;
}

解决方法
有一个类似的问题，这是为我解决的问题：
spring.hateoas:
use-hal-as-default-json-media-type: false
