java - 将文本转换为 URL

Question

有什么方法可以转换这样的请求:

"Annotation text="President Obama called Wednesday on Congress to extend a tax break
for students included in last year's economic stimulus package, arguing that the policy
provides more generous assistance."
confidence="0.2" support="20" 
sparql="SELECT DISTINCT ?x WHERE { ?x a <http://dbpedia.org/ontology/OfficeHolder>; . 
?x ?related <http://dbpedia.org/resource/Chicago>; }" 
policy="whitelist"

进入这个？

http://spotlight.dbpedia.org/rest/annotate?text=President%20Obama%20called%20Wednesday%20on%20Congress%20to%20extend%20a%20tax%20break%20for%20students%20included%20in%20last%20year%27s%20economic%20stimulus%20package,%20arguing%20that%20the%20policy%20provides%20more%20generous%20assistance.&confidence=0.2&support=20&sparql=SELECT+DISTINCT+%3Fx%0D%0AWHERE+%7B%0D%0A%3Fx+a+%3Chttp%3A%2F%2Fdbpedia.org%2Fontology%2FOfficeHolder%3E+.%0D%0A%3Fx+%3Frelated+%3Chttp%3A%2F%2Fdbpedia.org%2Fresource%2FChicago%3E+.%0D%0A%7D

我知道空格等于 %20，但我不知道其他转换。 有没有Java库可以进行转换？
