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; } }
