1.使用Jackson的ObjectMapper來實(shí)現(xiàn)，這種效果比較緊湊 先引入jackson的jar包：
<dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.9.13</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId> <version>2.7.0</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.6.0-rc2</version> </dependency>json格式化：
ObjectMapper mapper = new ObjectMapper(); mapper.configure(SerializationFeature.INDENT_OUTPUT, Boolean.TRUE);// json格式化設(shè)置（INDENT_OUTPUT表示支持縮進(jìn)）2.自己寫方法格式化，這種方式顯示效果比較好
public static String formatJson(String content) { StringBuffer sb = new StringBuffer(); int index = 0; int count = 0; while(index < content.length()){ char ch = content.charAt(index); if(ch == '{' || ch == '['){ sb.append(ch); sb.append('/n'); count++; for (int i = 0; i < count; i++) { sb.append('/t'); } } else if(ch == '}' || ch == ']'){ sb.append('/n'); count--; for (int i = 0; i < count; i++) { sb.append('/t'); } sb.append(ch); } else if(ch == ','){ sb.append(ch); sb.append('/n'); for (int i = 0; i < count; i++) { sb.append('/t'); } } else { sb.append(ch); } index ++; } return sb.toString(); }新聞熱點(diǎn)
