1.问题 : 因为业务需要,需要发送xml格式的数据,使用spring mvc 自己解析,就不用费心去自己搞这些东西.
2.解决:
新建一个实体类,直接在实体类中添加注解即可,如下:
@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class XMlTestBean {
@XmlElement
@XmlCDATA
private String username;
@XmlElement
private String password;
@XmlElement
private String name; public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
@Override
public String toString() {
return "XMlTestBean [username=" + username + ", password=" + password + ", name=" + name + "]";
} }
类上方添加:
@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
字段名添加:
@XmlElement
在controller类中返回即可:
@Controller
@RequestMapping("test")
public class TestController { @RequestMapping("xml")
@ResponseBody
public XMlTestBean getTestXML(){
XMlTestBean xml = new XMlTestBean();
xml.setUsername("aa");
xml.setPassword("bb");
xml.setName("cc");
return xml;
}
@RequestMapping("getXml")
public void getXml(@RequestBody XMlTestBean xml){
System.out.println(xml);
} }
结果:
<?xml version="1.0" encoding="UTF-8"?>
<xMlTestBean>
<username>
<![CDATA[aa]]>
</username>
<password>bb</password>
<name>cc</name>
</xMlTestBean>
补充:@XmlCDATA注解的作用:可以让返回值中添加
<![CDATA[]]>
CDATA 区段,可以不被XML解析器解析,但是需要在pom.xml添加
<dependency>
<groupId>org.eclipse.persistence</groupId>
<artifactId>eclipselink</artifactId>
<version>2.5.0</version>
</dependency>
和在实体类的包下添加jaxb.properties文件,文件内容如下:
javax.xml.bind.context.factory=org.eclipse.persistence.jaxb.JAXBContextFactory
只是解决了问题,但是原理这些还不懂,Σ( ° △ °|||)︴,有机会再搞懂原理吧
