文件操作

def file = new File('t.iml')
file.eachLine {
    line -> println line
}
println "--------------------1--------------------------"
def text = file.getText()
println text
println "--------------------2--------------------------"

def result = file.readLines()
result.each { println it.toString()}
println "---------------------3--------------------------"
//读取文件部分内容
def reader = file.withReader { reader ->
    char[] buffer = new char[100]
    reader.read(buffer)
    return buffer
}
println reader //只输出前100个字符

文件的复制

def rs = copy('t.iml', 't2.iml')
def copy(String sourcePath, String targetPath) {
    try {
        //首先创建目标文件
        def targetFile = new File(targetPath)
        if (!targetFile.exists()) {
            targetFile.createNewFile()
        }
        //开始copy
        new File(sourcePath).withReader { read ->
            def lines = read.readLines()
            targetFile.withWriter { writer ->
                lines.each { line ->
                    writer.append(line).append("\n")
                }
            }
        }
        return true
    } catch (Exception e) {
    }
}

文件的读写

println saveObject(new LawCase(id: "199", name: "jimmy"), "case.bin")
//对象的读写
def saveObject(Object obj, String targetPath) {
    try {
        //首先创建目标文件
        def targetFile = new File(targetPath)
        if (!targetFile.exists()) {
            targetFile.createNewFile()
        }
        targetFile.withObjectOutputStream { out ->
            out.writeObject(obj)
        }
        return true;
    } catch (Exception e) {
    }
    return false
}

println readObject("case.bin")

static def readObject(String path) {
    def obj = null
    try {
        //首先创建目标文件
        def file = new File(path)
        if (file == null || !file.exists()) {
            return null
        }
        file.withObjectInputStream { input ->
            obj = input.readObject()
        }
    } catch (Exception e) {

    }
    return obj
}
