SpringWebXML不考虑Java11中的XmlRootElement

我将我的应用程序迁移到JDK11（从JDK 8），因此我将升级到

springboot

2.2.4.版本

，并添加

com.fasterxml.jackson.dataformat:jackson dataformat xml

我的型号：

@XmlRootElement(name = "dataModel")
public class DataModel {
    ...
}

@RequestMapping(value = "/{model}/columns", method = RequestMethod.GET, consumes = MediaType.ALL_VALUE, produces = { MediaType.APPLICATION_XML_VALUE, MediaType.APPLICATION_JSON_VALUE })
public ResponseEntity<DataModel> getColumnsModel(@PathVariable String model) {
    LOGGER.info("getColumnsModel : model[{}]", model);
    DataModel dataModel = modelService.getColumns(model);
    return Optional.ofNullable(dataModel).map(result -> new ResponseEntity<>(result, HttpStatus.OK)).orElse(new ResponseEntity<>(HttpStatus.NO_CONTENT));
}

curl -s --header "Accept: application/xml" http://localhost:8084/api/foo/columns

<?xml version="1.0" encoding="UTF-8" standalone="yes"?><dataModel><columns>author</columns><columns>zip</columns><columns>city</columns><columns>element</columns><columns>element2</columns><columns>date</columns><columns>title</columns></dataModel>

<DataModel><columns><columns>author</columns><columns>zip</columns><columns>city</columns><columns>element</columns><columns>element2</columns><columns>date</columns><columns>title</columns></columns></DataModel>

我的控制器：

@XmlRootElement(name = "dataModel")
public class DataModel {
    ...
}

@RequestMapping(value = "/{model}/columns", method = RequestMethod.GET, consumes = MediaType.ALL_VALUE, produces = { MediaType.APPLICATION_XML_VALUE, MediaType.APPLICATION_JSON_VALUE })
public ResponseEntity<DataModel> getColumnsModel(@PathVariable String model) {
    LOGGER.info("getColumnsModel : model[{}]", model);
    DataModel dataModel = modelService.getColumns(model);
    return Optional.ofNullable(dataModel).map(result -> new ResponseEntity<>(result, HttpStatus.OK)).orElse(new ResponseEntity<>(HttpStatus.NO_CONTENT));
}

curl -s --header "Accept: application/xml" http://localhost:8084/api/foo/columns

<?xml version="1.0" encoding="UTF-8" standalone="yes"?><dataModel><columns>author</columns><columns>zip</columns><columns>city</columns><columns>element</columns><columns>element2</columns><columns>date</columns><columns>title</columns></dataModel>

<DataModel><columns><columns>author</columns><columns>zip</columns><columns>city</columns><columns>element</columns><columns>element2</columns><columns>date</columns><columns>title</columns></columns></DataModel>

JDK8:

@XmlRootElement(name = "dataModel")
public class DataModel {
    ...
}

@RequestMapping(value = "/{model}/columns", method = RequestMethod.GET, consumes = MediaType.ALL_VALUE, produces = { MediaType.APPLICATION_XML_VALUE, MediaType.APPLICATION_JSON_VALUE })
public ResponseEntity<DataModel> getColumnsModel(@PathVariable String model) {
    LOGGER.info("getColumnsModel : model[{}]", model);
    DataModel dataModel = modelService.getColumns(model);
    return Optional.ofNullable(dataModel).map(result -> new ResponseEntity<>(result, HttpStatus.OK)).orElse(new ResponseEntity<>(HttpStatus.NO_CONTENT));
}

curl -s --header "Accept: application/xml" http://localhost:8084/api/foo/columns

<?xml version="1.0" encoding="UTF-8" standalone="yes"?><dataModel><columns>author</columns><columns>zip</columns><columns>city</columns><columns>element</columns><columns>element2</columns><columns>date</columns><columns>title</columns></dataModel>

<DataModel><columns><columns>author</columns><columns>zip</columns><columns>city</columns><columns>element</columns><columns>element2</columns><columns>date</columns><columns>title</columns></columns></DataModel>

JDK11:

@XmlRootElement(name = "dataModel")
public class DataModel {
    ...
}

@RequestMapping(value = "/{model}/columns", method = RequestMethod.GET, consumes = MediaType.ALL_VALUE, produces = { MediaType.APPLICATION_XML_VALUE, MediaType.APPLICATION_JSON_VALUE })
public ResponseEntity<DataModel> getColumnsModel(@PathVariable String model) {
    LOGGER.info("getColumnsModel : model[{}]", model);
    DataModel dataModel = modelService.getColumns(model);
    return Optional.ofNullable(dataModel).map(result -> new ResponseEntity<>(result, HttpStatus.OK)).orElse(new ResponseEntity<>(HttpStatus.NO_CONTENT));
}

curl -s --header "Accept: application/xml" http://localhost:8084/api/foo/columns

<?xml version="1.0" encoding="UTF-8" standalone="yes"?><dataModel><columns>author</columns><columns>zip</columns><columns>city</columns><columns>element</columns><columns>element2</columns><columns>date</columns><columns>title</columns></dataModel>

<DataModel><columns><columns>author</columns><columns>zip</columns><columns>city</columns><columns>element</columns><columns>element2</columns><columns>date</columns><columns>title</columns></columns></DataModel>

新结果是strang:

@XmlRootElement(name = "dataModel")
public class DataModel {
    ...
}

@RequestMapping(value = "/{model}/columns", method = RequestMethod.GET, consumes = MediaType.ALL_VALUE, produces = { MediaType.APPLICATION_XML_VALUE, MediaType.APPLICATION_JSON_VALUE })
public ResponseEntity<DataModel> getColumnsModel(@PathVariable String model) {
    LOGGER.info("getColumnsModel : model[{}]", model);
    DataModel dataModel = modelService.getColumns(model);
    return Optional.ofNullable(dataModel).map(result -> new ResponseEntity<>(result, HttpStatus.OK)).orElse(new ResponseEntity<>(HttpStatus.NO_CONTENT));
}

curl -s --header "Accept: application/xml" http://localhost:8084/api/foo/columns

<?xml version="1.0" encoding="UTF-8" standalone="yes"?><dataModel><columns>author</columns><columns>zip</columns><columns>city</columns><columns>element</columns><columns>element2</columns><columns>date</columns><columns>title</columns></dataModel>

<DataModel><columns><columns>author</columns><columns>zip</columns><columns>city</columns><columns>element</columns><columns>element2</columns><columns>date</columns><columns>title</columns></columns></DataModel>

我尝试添加此依赖项，但未解决：

    <dependency>
        <groupId>javax.xml.bind</groupId>
        <artifactId>jaxb-api</artifactId>
        <version>2.3.1</version>
    </dependency>

    <dependency>
        <groupId>com.sun.xml.bind</groupId>
        <artifactId>jaxb-core</artifactId>
        <version>2.3.0.1</version>
    </dependency>

    <dependency>
        <groupId>com.sun.xml.bind</groupId>
        <artifactId>jaxb-impl</artifactId>
        <version>2.3.2</version>
    </dependency>

javax.xml.bind
jaxb api
2.3.1
com.sun.xml.bind
jaxb内核
2.3.0.1
com.sun.xml.bind
jaxb impl
2.3.2

删除此项：

<dependency>
    <groupId>com.fasterxml.jackson.dataformat</groupId>
    <artifactId>jackson-dataformat-xml</artifactId>
</dependency>

com.fasterxml.jackson.dataformat
jackson数据格式xml

不，不是。JDK11没有包含JAXB，现在它使用自己的XML编组而不是JAXB。在依赖项中包含JAXB，使其再次工作。与其盲目升级JDK版本，不如先阅读发行版中发生的发行说明/更改！我没有错误（在我的日志中），但我的xml结果是错误的

@M.Deinum，

jaxb api

，

jaxb核心

，

jaxb impl

都已在我的项目中准备就绪。此外，您应该删除jackson xml依赖项，因为现在将使用它而不是jaxb。
