struts2下实现的json传递list,object。
必须的jar：
java bean:
package upload.progress.action;
public class music {
private String name;
private String singer;
private String source;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSinger() {
return singer;
}
public void setSinger(String singer) {
this.singer = singer;
}
public String getSource() {
return source;
}
public void setSource(String source) {
this.source = source;
}
}
struts2.xml配置：
<?xml version="1.0" encoding="UTF-8" ?>
