1: javax.ws.rs jar出错

部署好后，点击查看restful后，出现以上错误，查看javax.ws.rs包，也没发现MessageProcessingException类，

maven依赖从2.0改为

<dependency>
<groupId>javax.ws.rs</groupId>
<artifactId>javax.ws.rs-api</artifactId>
<version>2.0-m10</version>
</dependency>

2.0.1页会出现此异常。

cxf采用的是2.9.11

可以点击查看异常说明

2：没有输出错误

No message body writer has been found for response class ArrayList.

spring配置文件修改：

<jaxrs:server id="***" address="/restful">
		......
		<jaxrs:providers>
			<bean class="com.fasterxml.jackson.jaxrs.json.JacksonJsonProvider"/>
		</jaxrs:providers>
	</jaxrs:server>

添加providers并增加maven依赖

<dependency>
            <groupId>com.fasterxml.jackson.jaxrs</groupId>
            <artifactId>jackson-jaxrs-json-provider</artifactId>
            <version>2.4.1</version>
        </dependency>
