使用java打开浏览器地址原理是通过 Runtime.getRuntime().exec(parts);命令打开本地默认浏览器,如果使用command指令打不开的话则使用jdk的 java.awt.Desktop.getDesktop().browse(uri); 打开
参考代码如下:
/**
* 打开浏览器访问URL
*/
public static void browsePage() {
TomcatEmbeddedServletContainerFactory tomcat = SpringBeanContextUtil.getBean("tomcatFactory",
TomcatEmbeddedServletContainerFactory.class);
String localhost = "localhost";
try {
localhost = NetUtil.getLocalHostLANAddress().getHostAddress();
} catch (UnknownHostException | SocketException e) {
LOGGER.error("获取本地ip失败:" + e.getMessage(), e);
}
try {
String url = "http://" + localhost + ":" + tomcat.getPort() + tomcat.getContextPath() + "/xxx";
// 调用默认浏览器
CommandUtil.browse(new URI(url));
} catch (URISyntaxException e) {
LOGGER.error("打开浏览器失败:" + e.getMessage(), e);
}
}CommandUtil类实现:
package xxx.util;
import java.awt.Desktop;
import java.io.File;
import java.io.IOException;
import java.net.URI;
import java.util.ArrayList;
import java.util.List;
