springmvc @ResponseBody相关配置

标签：

我想在程序里这么使用

@RequestMapping("/list")
	@ResponseBody
	public List<String> getList(){
		List<String> list=new ArrayList<String>();
		list.add("哈哈");
		list.add("哈哈");
		list.add("哈哈");
		list.add("哈哈");
		list.add("哈哈");
		return list;
	}

所以我需要进行一些配置，首先加入依赖

<dependency>
			<groupId>com.fasterxml.jackson.core</groupId>
			<artifactId>jackson-core</artifactId>
			<version>2.6.3</version>
		</dependency>
		<dependency>
			<groupId>com.fasterxml.jackson.core</groupId>
			<artifactId>jackson-databind</artifactId>
			<version>2.6.3</version>
		</dependency>
		<dependency>
			<groupId>org.codehaus.jackson</groupId>
			<artifactId>jackson-core-lgpl</artifactId>
			<version>1.9.13</version>
		</dependency>
		<dependency>
			<groupId>org.codehaus.jackson</groupId>
			<artifactId>jackson-mapper-asl</artifactId>
			<version>1.9.13</version>
		</dependency>
		<dependency>
			<groupId>org.codehaus.jackson</groupId>
			<artifactId>jackson-core-asl</artifactId>
			<version>1.9.13</version>
		</dependency>
		<dependency>
			<groupId>commons-fileupload</groupId>
			<artifactId>commons-fileupload</artifactId>
			<version>1.3.1</version>
		</dependency>

然后配置springmvc的配置文件

<!-- @ResponseBody注解支持-开始 -->
	<bean id="mappingJacksonHttpMessageConverter"
		class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
		<property name="supportedMediaTypes">
			<list>
				<value>application/json;charset=UTF-8</value>
			</list>
		</property>
	</bean>
	<bean
		class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />
	<bean
		class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
		<property name="messageConverters">
			<list>
				<bean id="utf8StringHttpMessageConverter"
					class="test.util.UTF8StringHttpMessageConverter" />
					<ref bean="mappingJacksonHttpMessageConverter" />
			</list>
		</property>
	</bean>
	<!-- @ResponseBody注解支持-结束 -->

注意其中的UTF8StringHttpMessageConverter

public class UTF8StringHttpMessageConverter extends StringHttpMessageConverter {
	private static final MediaType utf8 = new MediaType("text", "plain", Charset.forName("UTF-8"));
	private boolean writeAcceptCharset = true;
	@Override
	protected MediaType getDefaultContentType(String dumy) {
		return utf8;
	}

	protected List<Charset> getAcceptedCharsets() {
		return Arrays.asList(utf8.getCharSet());
	}

	protected void writeInternal(String s, HttpOutputMessage outputMessage)	throws IOException {
		if (this.writeAcceptCharset) {
			outputMessage.getHeaders().setAcceptCharset(getAcceptedCharsets());
		}
		Charset charset = utf8.getCharSet();
		FileCopyUtils.copy(s, new OutputStreamWriter(outputMessage.getBody(), charset));
	}

	public boolean isWriteAcceptCharset() {
		return writeAcceptCharset;
	}

	public void setWriteAcceptCharset(boolean writeAcceptCharset) {
		this.writeAcceptCharset = writeAcceptCharset;
	}

}

到此配置完成，留作备忘。
