Spring 4.2.0，Hibernate 4.1.4， 这是我的Controller功能：

@RequestMapping(value = "/mobile/getcomp", method = RequestMethod.GET)
@ResponseBody
public List<Company>  listforCompanies() {      
    List<Company> listOfCompanies= new ArrayList<Company>();        
    listOfCompanies = companyManager.getAllCompanies();
    return listOfCompanies;
}

Jackson JSON映射器依赖项Pom.xml：

    <!-- Jackson JSON Mapper -->
    <dependency>
        <groupId>org.codehaus.jackson</groupId>
        <artifactId>jackson-mapper-asl</artifactId>
        <version>${jackson.version}</version>
    </dependency>

在清单中获取列表ArrayList，但返回时显示以下错误：

SEVERE: Servlet.service() for servlet [dispatcherServlet] in context with path [/IrApp] threw exception [Request processing failed; nested exception is java.lang.IllegalArgumentException: No converter found for return value of type: class java.util.ArrayList] with root cause
