春季：使用构建器模式创建Bean

您可以尝试实现

FactoryBean

public class HttpFactoryBean implements FactoryBean<HttpClient>{private String host;private int port;public HttpClient getObject() throws Exception {    return new StdHttpClient.Builder()      .host(host)      .port(port)      .build();}public Class<? extends HttpClient> getObjectType() {    return StdHttpClient.class;}public boolean isSingleton() {    return true;}public void setHost(String host) {    this.host = host;}public void setPort(int port) {    this.port = port;}}

并添加到配置以下bean定义：

<beans ...">    <bean name="myHttpClient" >       <property name="port" value="8080"/>       <property name="host" value="localhost"/>   </bean></beans>

然后，您可以将此bean注入另一个bean，它将作为

StdHttpClient
