我要评论一、方式一，引用gson工具
测试报文：
{
"account":"yanxiaosheng",
"password":"123456"
}引入pom
<!-- https://mvnrepository.com/artifact/com.google.code.gson/gson --> <dependency> <groupid>com.google.code.gson</groupid> <artifactid>gson</artifactid> <version>2.6.2</version> </dependency>
测试类：
import com.google.gson.jsonelement;
import com.google.gson.jsonobject;
import com.google.gson.jsonparser;
@test
public void test() throws exception {
string json = "{\n" +
"\t\"account\":\"yanxiaosheng\",\n" +
"\t\"password\":\"123456\"\n" +
"}";
jsonparser jsonparser = new jsonparser();
jsonelement jsonelement = jsonparser.parse(json);
jsonobject jsonobject = jsonelement.getasjsonobject();
string fieldvalue = jsonobject.get("account").getasstring();
system.out.println(fieldvalue);
}
二、方式二，使用jackson
{
"account":"yanxiaosheng",
"password":"123456",
"flag":"true"
}测试类：
import com.fasterxml.jackson.core.jsonprocessingexception;
import com.fasterxml.jackson.databind.jsonnode;
import com.fasterxml.jackson.databind.objectmapper;
@test
public void test() throws exception {
string json = "{\n" +
"\t\"account\":\"yanxiaosheng\",\n" +
"\t\"password\":\"123456\",\n" +
"\t\"flag\":\"true\"\n" +
"}";
objectmapper objectmapper = new objectmapper();
jsonnode jsonnode = objectmapper.readtree(json);
string account = jsonnode.get("account").astext();
int password = jsonnode.get("password").asint();
boolean flag = jsonnode.get("flag").asboolean();
system.out.println(account);
system.out.println(password);
system.out.println(flag);
}三、方式三，使用jackson转换object
测试报文：
{
"account":"yanxiaosheng",
"password":"123456"
}测试类：
@test
public void test() throws exception {
string json = "{\n" +
"\t\"account\":\"yanxiaosheng\",\n" +
"\t\"password\":\"123456\"\n" +
"}";
objectmapper objectmapper = new objectmapper();
login login = objectmapper.readvalue(json, deposittest.login.class);
system.out.println(login.tostring());
}
public static class login{
private string account;
private string password;
public string getaccount() {
return account;
}
public void setaccount(string account) {
this.account = account;
}
public string getpassword() {
return password;
}
public void setpassword(string password) {
this.password = password;
}
@override
public string tostring() {
return "login{" +
"account='" + account + '\'' +
", password='" + password + '\'' +
'}';
}
}
注意！！！deposittest.login.class deposittest 需使用自己写的测试类名
四、方式四，使用hutool，获取报文数组数据
测试报文：
{
"code":"0",
"message":"",
"data":[{
"account":"yanxiaosheng",
"password":"123456"
}]
}引入pom
<dependency> <groupid>cn.hutool</groupid> <artifactid>hutool-all</artifactid> <version>4.1.19</version> </dependency>
测试类：
@test
public void test() throws exception {
string json = "{\n" +
"\t\"code\":\"0\",\n" +
"\t\"message\":\"\",\n" +
"\t\"data\":[{\n" +
"\t\t\"account\":\"yanxiaosheng\",\n" +
"\t\t\"password\":\"123456\"\n" +
"\t}]\n" +
"}";
jsonobject jsonobject = new jsonobject(json);
jsonarray jsonarray = jsonobject.getjsonarray("data");
jsonobject resultobject = jsonarray.getjsonobject(0);
string account = resultobject.getstr("account");
system.out.println(account);
}
