spring webservice 开发demo （实现基本的CRUD 数据库采用H2）

在实现过程中，遇到两个问题：

1： schema 写错：  

错误： http://myschool.com/schemas/st

正确： http://myschool.com/st/schemas    ---- schemas必须结尾才是schema  这个决定了Namspace

2: Response 对 server 端有 response 返回 需要通过采用jaxb实现

配置如下：

package school.info.pojo;

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlRootElement;

import org.springframework.stereotype.Component;

@Component
@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class FindByIdResponse {

    private Student student;

    public Student getStudent() {
        return student;
    }

    public void setStudent(Student student) {
        this.student = student;
    }
    
    
}
