标签： java json web-services maven jersey

我尝试在pom.xml中添加以下依赖项

<!-- Jersey-Json -->
    <dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-json</artifactId>
    <version>1.8</version>
    </dependency>

以及下面的web.xml

＆＃13;
＆＃13; 
<?xml version="1.0" encoding="UTF-8"?>

<web-app>
<servlet>
	<servlet-name>jersey-serlvet</servlet-name>
	<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
	<!-- <init-param>
		<param-name>com.sun.jersey.config.property.packages</param-name>
		<param-value>com.mkyong.rest</param-value>
	</init-param> -->
	<init-param>
		<param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
		<param-value>true</param-value>
	</init-param>
	<load-on-startup>1</load-on-startup>
  </servlet>
 
  <servlet-mapping>
	<servlet-name>jersey-serlvet</servlet-name>
	<url-pattern>/rest/*</url-pattern>
  </servlet-mapping>
</web-app>
＆＃13;
＆＃13;
＆＃13;

按照其他帖子。 但我还是得到了

我的代码如下：

@POST
@Path(PERSON_SALARY_PATH)
@Produces(MediaType.APPLICATION_JSON)
public String getSalary(@RequestBody RequestCDTO requestCDTO) {

2 个答案:

答案 0 :(得分：5)

在我的代码中，它在添加依赖项

之后起作用 
<dependency>
        <groupId>org.jboss.resteasy</groupId>
        <artifactId>resteasy-jackson2-provider</artifactId>
        <version>3.0.19.Final</version>
    </dependency>

答案 1 :(得分：2)

添加@Consumes（MediaType.APPLICATION_JSON）并确保设置请求标头“Content-Type：application / json”。前者我认为不是必需的，但无论如何你应该离开它。后者是最重要的。出于某种原因，您的请求将以“text / plain”标题发送出去

peeskillet的上述评论是正确的答案。
