我正在尝试编写搜索API的GET请求。我正在编写它public class ApplicationDirectories {
private static final Logger logger =
Logger.getLogger(ApplicationDirectories.class.getName());
private static final Path config;
private static final Path data;
private static final Path cache;

String os = System.getProperty("os.name");

data = config;
cache = config;
} else if (os.contains("Windows")) {
String version = System.getProperty("os.version");
if (version.startsWith("5.")) {
config = getFromEnv("APPDATA", false,
Paths.get(home, "Application Data"));
data = config;

，但我得到的是404.如果我将其写为http://localhost:8280/solr/1.0/search?searchText=abc，我就能获得JSON响应数据。
我写的是http://localhost:8280/solr/1.0/并使用网址/*获取回复。
如果我将其写为http://localhost:8280/solr/1.0/我没有收到404（/search*）。
我哪里出错？

启用wirelogs并检查从AM发送到Backend的请求类型。您可能能够找到原因。请参考http://mytecheye.blogspot.com/2013/09/wso2-esb-all-about-wire-logs.html以启用和分析日志
