公共静态列表getAddressBooleanExpressions（字符串类型，类clazz）{         列表booleanExpressions = new ArrayList（）;         PathBuilder entityPath = new PathBuilder（clazz，type）;         BooleanExpression expression1 = entityPath.get（“ column1”）。eq（entityPath.get（“ column2”））;;         BooleanExpression expression2 = entityPath.get（“ columnA”）。eq（entityPath.get（“ columnB”））;         BooleanExpression expression3 =实体路径.get（“ columnX”）。eq（entityPath.get（“ columnZ”））;         BooleanExpression expression4 = entityPath.get（“ physicalAddress”）.eq（entityPath.get（“ mailingAddress”））;
        booleanExpressions.add（expression1）;         booleanExpressions.add（expression2）;         booleanExpressions.add（expression3）;         booleanExpressions.add（expression4）;         return booleanExpressions;
