Suppose you want to prevent unauthorized users to access the page then you have to put barrier. to them by authorizing access We can do this by using spring security which provides basic. authentication by securing all HTTP end points For that you need to add spring security. dependency to your project in maven we can add the dependency as. dependency,groupId org springframework boot groupId.
artifactId spring boot starter security artifactId. dependency, Here s a security configuration that ensures that only authenticated users can access. Configuration,Order SecurityProperties ACCESS OVERRIDE ORDER. public class SecurityConfig extends WebSecurityConfigurerAdapter. DataSource datasource, protected void configure HttpSecurity http throws Exception. authorizeRequests,anyRequest,fullyAuthenticated,loginPage login. failureUrl login error,logoutUrl logout,logoutSuccessUrl login logout.

protection is enabled,Overridden method to define, configure AuthenticationManagerBuilder how the users are. authenticated,Indicates to spring that we, jdbcAuthentication dataSource datasource are using JDBC. authentication,Indicates to spring that we,are using a password. encoder to encode our, passwordEncoder passwordEncoder passwords A bean is. created to return the choice,of password Encoder we are.
using BCrypt in this case, Notice that we have not configured any table name to be used or any query this is because spring. security by default looks for the below tables,create table users. username varchar 50 not null primary key,password varchar 255 not null. enabled boolean not null,create table authorities,username varchar 50 not null. authority varchar 50 not null,foreign key username references users username.
unique index authorities idx 1 username authority,Insert the following rows into the above tables. INSERT INTO authorities username authority,VALUES user ROLE ADMIN. INSERT INTO users username password enabled, VALUES user 2a 10 JvqOtJaDys0yoXPX9w47YOqu9wZr PkN1dJqjG9HHAzMyu9EV1R4m 1. The username in our case is user and the password is also user encrypted with BCrypt algorithm. Finally Configure a datasource in the application properties for spring boot to use. spring datasource url jdbc mysql localhost 3306 spring. spring datasource username root,spring datasource password Welcome123. https riptutorial com 6, Note Create and configure a login controller and map it to the path login and point your login.
