创建SAPUI5 Application
创建Application,并创建XML view,在view1.view.xml的content标签内创建table组件内容
在web.xml中,添加SimpleProxyServlet的参数
在view1.controller.js中,添加init方法
onInit: function() {
// var oModel = new sap.ui.model.odata.ODataModel("proxy/sap/opu/odata/sap/ZLL_DEMO_SRV/");
var oModel = new sap.ui.model.odata.v2.ODataModel("proxy/sap/opu/odata/sap/ZLL_DEMO_SRV/", {
json : true,
user : "username",
password : "Password"
});
this.getView().setModel(oModel);
},
解决PKIX:unable to find valid certification path to requested target 的问题:对于https,需要导入证书,创建InstallCert class

public void checkServerTrusted(X509Certificate[] chain, String authType)
throws CertificateException {
this.chain = chain;
tm.checkServerTrusted(chain, authType);
}
}
}
编译InstallCert.java,然后执行:java InstallCert hostname
输入1,回车,然后会在当前的目录下产生一个名为“ssecacerts”的证书。将证书拷贝到$JAVA_HOME/jre/lib/security目录下,重启服务器,可以看到调用成功。
修改UI
给table添加SingleSelect属性
添加CRUD4个按钮
并在controller中创建相应的方法
onDisplay: function(){
},
onUpdate: function(){
},
onCreate: function(){
},
onDelete: function(){
},
添加Simple Form,拷贝Change.fragment.xml中的Grid代码
最终view的代码如下
UI如图
可以在init方法中令grid不显示
var oGrid = this.getView().byId("GridId");
oGrid.setVisible(false);
