使用Spring Boot的Jersey多部分配置
使用Spring Boot的Jersey多部分配置
提问于 2018-05-31 23:50:56
我在尝试解析包含多部分文件的HttpServletRequest时遇到问题。我已经尝试了关于我面临的异常的其他帖子的所有解决方案，但似乎都不起作用。
以下是项目的相关依赖项：
<project>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.13.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jersey</artifactId>
</dependency>
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-multipart</artifactId>
<version>2.25.1</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>commons-fileupload</groupId>
<artifactId>commons-fileupload</artifactId>
<version>1.3.3</version>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
</plugins>
</build>
SpringBoot应用程序初始化器：
@SpringBootApplication
public class ApplicationBoot extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(ApplicationBoot.class);
}
public static void main(String[] args) {
SpringApplication.run(ApplicationBoot.class, args);
}
}Jersey初始化器配置和multipartResolver bean：
@Configuration
@ApplicationPath("/rest")
public class JerseyConfig extends ResourceConfig {
public JerseyConfig() {
register(AttachmentResource.class);
register(ContentResource.class);
register(MultiPartFeature.class);
}
@Bean(name = "multipartResolver")
public CommonsMultipartResolver multipartResolver() {
CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();
multipartResolver.setMaxUploadSize(100000);
return multipartResolver;
}
}以及我所面临的关于多部分解析的问题的类，以及资源：
@Component
@Path("/attachments")
public class AttachmentResource {
@POST
@Path("/store")
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces(MediaType.APPLICATION_JSON)
public Response store(@Context HttpServletRequest httpRequest) {
for (Part part : httpRequest.getParts()) {
...
}
}
}当调用getParts()时，我收到java.lang.IllegalStateException: Unable to process，因为没有提供多部分配置
我在application.properties中添加了以下属性：
spring.http.multipart.enabled=true
spring.http.multipart.max-file-size=100MB
spring.http.multipart.max-request-size=100MB
spring.http.multipart.file-size-threshold=0这也是SpringBoot在启动时启用调试输出时记录的关于多部分配置的内容：
=========================
AUTO-CONFIGURATION REPORT
=========================
Positive matches:
-----------------
MultipartAutoConfiguration matched:
- @ConditionalOnClass found required classes 'javax.servlet.Servlet', 'org.springframework.web.multipart.support.StandardServletMultipartResolver', 'javax.servlet.MultipartConfigElement'; @ConditionalOnMissingClass did not find unwanted class (OnClassCondition)
- @ConditionalOnProperty (spring.http.multipart.enabled) matched (OnPropertyCondition)
MultipartAutoConfiguration#multipartConfigElement matched:
- @ConditionalOnMissingBean (types: javax.servlet.MultipartConfigElement; SearchStrategy: all) did not find any beans (OnBeanCondition)
Negative matches:
-----------------
MultipartAutoConfiguration#multipartResolver:
Did not match:
- @ConditionalOnMissingBean (types: org.springframework.web.multipart.MultipartResolver; SearchStrategy: all) found bean 'multipartResolver' (OnBeanCondition)稍后编辑：
如果我将应用程序部署在独立的tomcat 8中，并将其添加到con/context.xml中，则它可以工作：
<Context allowCasualMultipartParsing="true">或者在项目中的src/main/webapp/META-INF下添加一个context.xml文件：
<?xml version="1.0" encoding="UTF-8"?>
<Context path="" allowCasualMultipartParsing="true"/>但如果我使用嵌入式Tomcat启动项目，它就不起作用了。

这不是如何在新泽西使用MultiPart的。如果想要获取所有部分，可以使用FormDataMultiPart作为实体参数
@POST
public Response post(FormDataMultiPart multiPart) {
Map<String, List<FormDataBodyPart>> parts = multiPart.getParts();
}如果希望按名称获取注入单个部件，则可以使用@FormDataParam注释，将部件的名称传递给该注释。
@POST
public Response post(@FormDataParam("file") InputStream file,
@FormDataParam("file") FormDataContentDisposition fileDatail) {
}另请参阅
