我有两个springboot项目-a(带有api的主要大型项目)和b(a作为pom.xml中的依赖项导入的库)
项目b的pom.xml:

项目中有返回json对象的api。但在集成测试中,它们以xml格式返回数据,导致失败。只有在a中使用库b时才会发生这种情况。如果我们把b从a中去掉,那么所有的测试都通过了。
这是错误消息:
org.json.JSONException: Unparsable JSON string: <ResponseDTO>.....</ResponseDTO>
我的猜测是,这两个项目的依赖性之间存在某种冲突。但无法精确地指出哪个依赖项。
我的猜测是,由于spring使用jackson将返回的对象转换为json,并且项目b中存在一个依赖项,因此它可能与这个库有关:
<dependency>
<groupId>com.fasterxml.jackson.dataformat</groupId>
<artifactId>jackson-dataformat-xml</artifactId>
<version>2.9.8</version>
</dependency>
但我不明白这会有什么影响。如果需要更多的信息,请告诉我。
编辑1:添加控制器代码:
testdto.java文件
@Data // lombok annotation
public class TestDTO {
@JsonProperty(value = "id")
@JsonSetter(nulls = Nulls.AS_EMPTY)
private String id;
@JsonProperty(value = "name")
@JsonSetter(nulls = Nulls.AS_EMPTY)
private String name;
}
testcontroller.java测试控制器
@RestController
public class TestController {
@Autowired
private final TestService testService;
@GetMapping("/test/:id")
public TestDTO get(@PathVariable String id) {
return testService.get(id);
}
}
**编辑2:**添加了请求-响应头
请求
HTTP Method = GET
Request URI = /test/1
Parameters = {}
Headers = [Content-Type:"application/json", Content-Length:"616"]
Body = <no character encoding set>
Session Attrs = {}
响应
Status = 200
Error message = null
Headers = [Content-Type:"application/xml;charset=UTF-8"]
Content type = application/xml;charset=UTF-8
Body = <TestDTO>...</TestDTO>

可能是这样,因为springboot通过依赖关系b获取xml解析库。
我要么在Map中定义products属性,要么配置
WebMvcConfigurer
将json设置为默认类型。为此,请添加
WebMvcConfigurer
在某个地方。即使在依赖关系中,如果它在相同的spring上下文中运行,那么b也可以。这适用于Spring Boot2.4.2:
