版主環境介紹 spring 4.1.6 + springmvc 4.1.6 + mybatis3.3..1 版本的框架
SSM框架maven 項目
--------------------------------------------------------------------------------------------------------------------------------------
1、配置ajax所需 jar 包依賴 4個，
pom.xml文件直接添加以下4個座標即可；
<!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-annotations -->
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-annotations</artifactId>
<version>2.6.0</version>
</dependency>
<!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-core -->
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.6.0</version>
</dependency>
<!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind -->
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.6.0</version>
</dependency>
<!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.jr/jackson-jr-all -->
<dependency>
<groupId>com.fasterxml.jackson.jr</groupId>
<artifactId>jackson-jr-all</artifactId>
<version>2.6.0</version>
</dependency>
-------------------------------------------------------------------------------------------------------------------------------------
2、修改spring-servlet.xml 文件
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="messageConverters">
<list>
<ref bean="mappingJackson2HttpMessageConverter" />
</list>
</property>
</bean>
<bean id="mappingJackson2HttpMessageConverter"
class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>application/json;charset=UTF-8</value>
<value>text/html;charset=UTF-8</value>
<value>text/json;charset=UTF-8</value>
</list>
</property>
</bean>
-----------------------------------------------------------------------------------------------------------------------------------------------
總結：
調整完畢以上配置，直接更新項目發佈即可進行調試，建議使用簡單的 maven 項目或 webproject 進行調試，避免其他因素干擾測試結果
