Java 删除{}之间的空格 “${addr2}${addr1}${zipcd}${city}”${addr2}${addr1}${addr2}${addr3}${cntry_desc}好的

我希望输出为

<#if  {   cntry  }  =  "FI"  >  <#if  {   addr2  }  =  " "  >" "  <#else> ${  addr2   }    </#if>  ${   addr1  }    ${   zipcd  }   ${   city  }      <#else> <#if  {   addr2  }  =  " "  >" "  <#else> ${  addr2   }    </#if>  ${   addr1  }    ${   addr2  }   ${   addr3  }    ${   cntry_desc  }  ok fine  </#if>

“${addr2}${addr1}${zipc}${city}”${addr2}${addr1}${addr2}${addr3}${cntry_desc}好的

只想删除{}

之间的空格就可以了

<#if  {cntry}  =  "FI"  >  <#if  {addr2}  =  " "  >" "  <#else> ${addr2}    </#if>  ${addr1}    ${zipc}   ${city}      <#else> <#if  {addr2}  =  " "  >" "  <#else> ${addr2}    </#if>  ${addr1}    ${addr2}   ${addr3}    ${cntry_desc}  ok fine  </#if>

只要

{

和

}

没有嵌套，就可以使用此正则表达式搜索：

str = str.replaceAll("\\{\\s*", "{")
         .replaceAll("\\s*\\}", "}")

并将其用于替换：

" +(?=[^{]*})"

Java代码：

""

或者你可以使用

String repl = input.replaceAll(" +(?=[^{]*})", "");

和使用

\{\s+([\w]+)\s+\}

作为替代

所以，这个代码

{$1}

String raw=“\”\“${addr2}${addr1}${zipcd}${city}\”\“${addr2}${addr1}${addr2}${addr3}${cntry\u desc}好的”；
raw.replaceAll（“\\{\\s+（[\\w]+）\\s+\\}，“{$1}”）；

会回来的

String raw = "<#if  {   cntry  }  =  \"FI\"  >  <#if  {   addr2  }  =  \" \"  >\" \"  <#else> ${  addr2   }    </#if>  ${   addr1  }    ${   zipcd  }   ${   city  }      <#else> <#if  {   addr2  }  =  \" \"  >\" \"  <#else> ${  addr2   }    </#if>  ${   addr1  }    ${   addr2  }   ${   addr3  }    ${   cntry_desc  }  ok fine  </#if>";
raw.replaceAll("\\{\\s+([\\w]+)\\s+\\}", "{$1}");

“${addr2}${addr1}${zipcd}${city}”${addr2}${addr1}${addr2}${addr3}${cntry_desc}好的
