controller要接收List<myObject>之类的泛型数据，需要在springmvc中添加json相关的解析配置。

主要是添加：<bean class="org.springframework.web.servlet.view.json.MappingJackson2JsonView" />

具体示例如下：

Bean - CustomInfo:

public class CustomInfo {/* 包含一个List<CustomRule> */private List<CustomRule> ruleList;private List<String> objList;private String objType;/* getters and setters */@Overridepublic String toString() {String rule = "";for(CustomRule cRule: ruleList) {rule += cRule.toString() + "\n";}return "customRules\n" +"ruleList=" + rule + "\n" +"objList=" + objList.toString() +  "\n" +"objType: " + objType + "\n\n";}}

Bean - CustomRule

public class CustomRule {private String metricType;private String startDate;private String endDate;private String startHour;private String endHour;/* getters and setters */@Overridepublic String toString() {return "metricType: " + metricType + "  startHour: " + startHour + "  endHour: " + endHour + "  startDate: " + startDate + "  endDate: " + endDate; }
}

js：

data = [{"objType": "testType1", "objList": ["obj1", "obj2", "obj3"], "ruleList": [{"metricType": "test1", "startHour": "1"}]}, {"objType": "testType2", "objList": ["obj1", "obj2", "obj3"], "ruleList": [{"metricType": "test2", "startHour": "2"}]}]$.ajax({url : "xxx/test",data: JSON.stringify(data),type : "post", dataType : "json",contentType: "application/json; charset=utf-8",success: function(data) {  if (data.success == true) {console.log(data.msg);/* TO-DO： 跳转到定制页面 */} else {alert("添加失败, 失败原因： " + data.msg);}},error: function (e) {console.log(e);}});

controller:

@RequestMapping(value="/test", method=RequestMethod.POST)@ResponseBodypublic Json test(@RequestBody List<CustomInfo> data) {DataSourceContextHolder.setDataSource(DataSource.dbprod_dataSource); Json j = new Json();try {for (CustomInfo c: data) {System.out.print(c.toString());}j.setSuccess(true);j.setMsg("insert sucess!");} catch (Exception e) {System.out.println(e.toString());j.setSuccess(false);j.setMsg(e.getMessage());}return j;
}

springmvc.xml中添加以下配置：

<beanclass="org.springframework.web.servlet.view.ContentNegotiatingViewResolver"><property name="order" value="1" /><property name="contentNegotiationManager"><bean class="org.springframework.web.accept.ContentNegotiationManager"><constructor-arg><beanclass="org.springframework.web.accept.PathExtensionContentNegotiationStrategy"><constructor-arg><map><entry key="json" value="application/json" /><entry key="xml" value="application/xml" /></map></constructor-arg></bean></constructor-arg></bean></property><property name="defaultViews"><list><beanclass="org.springframework.web.servlet.view.json.MappingJackson2JsonView" /><bean class="org.springframework.web.servlet.view.xml.MarshallingView"><constructor-arg><bean class="org.springframework.oxm.xstream.XStreamMarshaller"><property name="autodetectAnnotations" value="true" /></bean></constructor-arg></bean></list></property></bean>

我使用的是maven，需要添加以下的jar包：

<!-- JACKSON -->
<dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-annotations</artifactId><version>2.2.1</version>
</dependency>
<dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-core</artifactId><version>2.2.1</version>
</dependency>
<dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-databind</artifactId><version>2.2.1</version>
</dependency>
<dependency><groupId>org.springframework</groupId><artifactId>spring-oxm</artifactId><version>4.0.6.RELEASE</version>
</dependency>
<dependency><groupId>com.thoughtworks.xstream</groupId><artifactId>xstream</artifactId><version>1.4.7</version>
</dependency>
