struts2 嵌套list属性的显示与form提交

来源：互联网发布：鹿晗颜值如何知乎编辑：程序博客网时间：2024/06/15 20:31

action中有如下List属性，需要能显示到jsp页面并通过页面修改值提交form到action:

private List<Section> sectionsList;

Section类如下，其中Section中又包括一个Field的List

public class Section implements Serializable {private static final long serialVersionUID = 3952189513312630860L;private String name;private String nameTranslate;private List<Field> fields;public String getName() {return name;}public void setName(String name) {this.name = name;}public String getNameTranslate() {return nameTranslate;}public void setNameTranslate(String nameTranslate) {this.nameTranslate = nameTranslate;}public List<Field> getFields() {return fields;}public void setFields(List<Field> fields) {this.fields = fields;}}

Field类如下：

public class Field implements Serializable {private static final long serialVersionUID = 3952189513312630860L;private String code;private String label;private String labelTranslate;private String defaultValue;private String overrideValue;public String getCode() {return code;}public void setCode(String code) {this.code = code;}public String getLabel() {return label;}public void setLabel(String label) {this.label = label;}public String getLabelTranslate() {return labelTranslate;}public void setLabelTranslate(String labelTranslate) {this.labelTranslate = labelTranslate;}public String getDefaultValue() {return defaultValue;}public void setDefaultValue(String defaultValue) {this.defaultValue = defaultValue;}public String getOverrideValue() {return overrideValue;}public void setOverrideValue(String overrideValue) {this.overrideValue = overrideValue;}}

JSP页面如下些，则可将action中的sectionsList与form关联：
